The only reason they object to presenting ID is because it will prevent election fraud.
That is it. Progressives are ALWAYS for more red tape, more rules...except when those rules will expose them or prevent them from stealing what they want.
Voter fraud has happened so little (around 10 times) and it was usually felons who didn't know they had lost the right to vote.
The only reason for the voter ID right now is to suppress the Democratic vote, which is why they did it in PA, and why early voting is being targeted in Democratic districts in Ohio but not the Republican ones.
Actually, there is really no way to know how much vote fraud has occurred because the vast majority of it is ineligible people registering and voting in their own names. Unless voter registration rolls are compared to citizenship roles you will NEVER know how much fraud occurs. This is why valid ID is so important. Illegal aliens are unable to OBTAIN ID in most states, and if they ARE able their status, as with legal aliens, will be noted on that ID, effectively preventing them from casting an illegal vote.
I don't know about you, but I don't want non-citizens voting in our elections, PERIOD.
