Re: I hate to say this, but it's sad that there are homo sapiens so f'in stupid
Somehow, you seem to be labouring under the mistaken impression that this is a conversation that has anything to do with Democrats or Republicans. If you look carefully, you'll see I've said nothing of political parties: I merely pointed out that the problem exists. I've now linked to two articles confirming it as an issue: one from a slightly left-leaning source, and the other from a slightly right-leaning source.
However, if you want to talk about US political parties, then I shall declare my own position. Perhaps it's easiest to explain if I note that the Democrats and the Republicans, while considered vaguely "Left" and "Right", respectively, across the pond, actually fit better into "Right" and "Hard Right" if you consider the definitions across most of continental Europe. As such, I'm not really very fond of either. As far as I can see, the Republicans are the most recent and most prolific offenders regarding voter suppression, particularly when it comes to minorities. However, frankly, I don't think that's relevant, surprising, or even particularly interesting.
