I think Trump is shooting himself in the foot in this situation. How many people can you arrest, or heaven forbid, shoot? The article claims he is using this to further incite fear and the us-and-them-mentality. I'm not sure how long voting goes on for. I believe it started today but is it a one-day affair or continue for a few days. If it's the latter, maybe he take whatever extra votes he can scare up from this situation and then take a light touch when the immigrants arrive.
The Republicans and Democrats are now fully discredited as big business partys, I think large sections of the working class won't vote either in as for Donald Trump he's trying to instill fear but I can't see the workers voting for his party in large numbers because this type of immigrant bating isn't popular yet.
