State Caucus or Primary Election?

I came into voting age in the state of Florida, which had always had a state primary election since we moved there in 1961.  I moved back and forth between Florida and Virginia between 1982 and 2004, and I always voted in local, state, and Presidential elections by filling out a ballot.  I moved to Colorado in late 2004, and for the first time in my life had to participate in a Caucus.  I did not like it in any way, shape, or form.  I was yelled at and derided for my opinions. (I admit I was one of 8 people over the age of 25, out of a group of 62 people.  And the younger people were extremely rude. That made me dislike even the idea of attending the next Caucus, but I did.)  The city of Boulder - and Colorado in general - has had a huge influx of population in the past 8 to 10 years.  When I went to Caucus for the 2016 election, even though I arrived 45 minutes before it was scheduled to begin, the venue was already packed to capacity, and there were several hundred people who arrived at their designated caucus place, who could not participate, because we could not get inside the door.  This happened all over the state of Colorado - and a majority of voters complained that their voices were not heard in the caucus.  This year, 2020, we are having the first Primary election in 20 years.  (The caucus system was adopted by the Colorado legislature in a special session called by Governor Shafroth in August 1910, as a part of a package of progressive reforms. It was seen as a way to  limit the power of political party bosses, and to attract more grassroots involvement.  The caucus system was abolished in favor of the Presidential primary in 1992, but was restored in 2002.)  I have been notified by the Boulder County Clerk's Office that my ballot will be mailed to me on 10 February 2020.  I will vote for the candidate of my choice, sign and date the ballot, seal it, and return it to the County Clerk's Office.  Easy-peasy.

   By definition, a caucus is any political group or meeting organized to further a special interest or cause.
   The word caucus originated in Boston, Massachusetts in the early part of the 18th century, when it was used as the name of a political club, the Caucus, or Caucus Club.  The club hosted public discussions and the election of candidates for public office.  In its subsequent and current usage (in the US), the term came to denote a meeting of either party managers, or duty voters, as in "nominating caucus," which nominates candidates for office or selects delegates for a nominating convention. The caucus of a party's members in Congress nominated its candidates for the office of President and Vice President from 1796 until 1824. At the same time, the candidates for Governor and Lieutenant Governor were nominated by the party members of the State Legislatures in what was known as the legislative nominating caucus. Occasionally, districts unrepresented in the legislature sent in delegates to sit in with the members of the legislature when these nominations were made, and this was termed the mixed legislative nominating caucus.
   Here in America, the use  of the term "caucus" denotes a faction within a legislative body that attempts to further its interests by influencing either party policy on proposed legislation or legislative offices; hence such bodies as the Black Caucus (representing African Americans), the Women's Caucus, the Hispanic Caucus, the Freedom Caucus, and the Progressive Caucus, to name a few.
   North Dakota and Wyoming will hold political conventions to decide their Republican candidate; North Dakota will also hold a primary for Democrats, while Wyoming will hold a caucus for the Democrats.
   Those places holding a caucus are: Nevada, American Samoa, Guam, the Northern Marianas, the American Virgin Islands, and Iowa.
   All other states will hold Primary voting for both parties, except the following states who have already decided, without any competition, that Donald Trump will be their Republican nominee: Alaska, Arizona, Hawai'i, Kansas, Nevada, South Carolina, and Virginia.

   Iowa held its caucus Monday night, 3 February, 2020.  Instead of using their old tried and true method, the Democratic party there decided to use a new hand-held application to tabulate the results. The country is still waiting for the final results of the caucus, which is usually announced in the early hours of Tuesday.  Nevada is going to caucus on Saturday, 22 February, and was supposed to use the same app to tally their results.  They announced that they will be using the old method, now.
   The Iowa caucus was never heralded until the 1976 caucus, when Jimmy Carter, to everyone's surprise, was declared the winner.  He went on to win the Democratic nomination that year, and to win the Presidency, as well. Since that time, the media has zeroed in on the Iowa caucus as a true indicator of the country's feelings.  But it has been very wrong in the past, as well....

   My personal feeling is that each state, the District of Columbia, and each territory should have a Primary for the Presidency.  Over-crowding, bad weather, and illness epidemics can, and will, always affect the people who can, and will, show up.  I believe that a Primary system with ballots that arrive by mail, and are returned by mail, or in person, are the best way to vote in this day and age.  Why?  Because caucuses really don't work for any of the above stated reasons, and people who have an illness or handicap or an aversion to crowds might not be able to attend, even though they want to. Therefore, some people will always be disenfranchised from a caucus.
   Voting by computer from home or work is out of the question.  There is too much hacking and stealing of passwords and personal identities.
   Going to a voting center to cast your vote in person can also be problematic.  You're ill; your car breaks down; there's a traffic accident; you don't have transportation to your designated voting place; you're in the hospital; your place of work will not allow you to come in late or leave early to vote (even though it's a federal law that they must); there's a long line ahead of you and the polling place doors are shut before you get inside.  - The list goes on and on.
   That's one  of the reasons I love the current voting system for (now) all elections.  You go into the County Clerk's Office and register once.  You show them your identification with your current address, if your mailing address is different you provide that, you mark which party you wish to be affiliated with (Democrat, Republican, or Other), you sign the form, and you are a registered voter. (If you move, you send your new mailing address to the County Clerk's Office by e-mail.) For each election, you receive your ballot in the mail, you mark it, date it and sign it. Then you can either mail it back, or drop it off at one of many designated locations throughout the city (or county). You receive an e-mail stating they have received your ballot.  Then you receive an e-mail stating that your ballot and vote has been approved and counted.  If there are any problems with your ballot, you receive notification of what the problem is, and how to remedy it.
   I am all for Primary Elections and against a caucus.....
