Well, the people in this thread talking about 'fighting back', are, in a certain sense, correct. I mean, if the Democrats had the ability to disenfranchise Republicans, then they undoubtedly would do so.
The Democrats controlled all but a few state legislatures 30 years ago. But I don't know of any instances back then where Republicans were turned away when they tried to vote.
Of course, of course. I mean, when I say 'ability', simply being in government doesn't give you the ability to do certain things. After all, especially thirty years ago, Republican voters tended to be better off, and its far harder to disenfranchise better off people without making it look like (or at least giving the facade of it looking like that) they're being deliberately disenfranchised than it is for poorer people to be disenfranchised in that type of way. I'm not making any comments about the morality of such moves, I'm simply stating that, if Democrats could do so, then most Democrats would do so, just as most Republicans would.
