it wont be an issue if they all have id's..if anything the absentee (republican) votes will become more of a pain as u will have to pre-register with an id somehow.
But it is an issue because they don't have IDs. That's the point. In Indiana, only 83% of Democrats had IDs that would allow them to vote.
I'd also point out, again, that there is little evidence of voter fraud of the type that voter ID laws are designed to stop. Why disenfranchise 17% of Democrats if there is no real reason to do so? Because disenfranchising Democrats is the whole point.
