In the 2020 presidential election, the average state had six presidential candidates on the ballot. The median state had five candidates. The average is somewhat distorted because Colorado and Vermont each had 21 candidates, so the median is probably a more meaningful figure.
Twelve states only had three candidates on the ballot: Alabama, Arizona, Georgia, Indiana, Kansas, Montana, Nebraska, New Hampshire, North Dakota, Pennsylvania, South Dakota, and Virginia.
If you intend to ask any state legislator to introduce a bill to ease ballot access, and you are in one of the twelve states that only had three, that is ammunition for the idea that your state is too difficult.
In the early Democratic presidential primaries, every state had at least 12 Democrats on the presidential primary ballot, and that didn’t cause any “voter confusion” problems. The same is true of early Republican presidential primaries in 2016.
Ballot access laws that keep worthy candidates off the ballot don’t only injure those candidates. They injure the voters who would like to vote for such candidates. Democratic Party legislators like to think that the Democratic Party is a champion of voting rights, so if you are communicating with a Democratic state legislator, make this point.
