Yes, they would...Voter suppression has been used very often in the past, mostly by republicans...
would you like me to cite examples of this stuff in the past, well I dont care I'm gonna anyways..
Milwaukee-
pamphlets were handed out in a black neighboorhood with heading "Black Voters League" warning citizens that if they had already voted that year, they were ineligable for voting in the presidential election, also, if they or any family member had commited any crime, however minor, they were inelligible...
Allegheny County Pennsylvania-
flyers were handed out claiming "Due to immense voter turnout expected on Tuesday, Nov 2, the state of Pennsylvania has requested an extended voting period. Voters will be able to vote on the 2nd AND 3rd. In an attmept to limit voter conflict, Allegheny County is requesting that Republican voters vote on the 2nd and Democrat voters on the 3rd.
I can go on with litierally dozens of these type of things...
