A commentary Sunday in Florida Politics by Jeffrey Solomon was critical of the Democratic Party for its opposition to open primaries. He said it disenfranchises independent voters (true) and keeps the party from widening its base (debatable).
He said that’s why he left the party and became an independent.
The issue is not going away. There is a drive to place the issue on the ballot as an amendment in 2020 to the state constitution.
The question of whether to open primaries to all registered voters has done the impossible. Republicans and Democrats are actually united around something besides mom and apple pie. They oppose open primaries.
