Umm... Rosie, have you actually looked at how immigrants who have been here for a while or their children vote? Have you talked to any? My take is they are mostly moderate to mildly conservative. That is what got Arnold elected, he got a lot of the hispanic vote which surprised almost everybody. Well guess what, I don't have the numbers but I bet you the ones that voted for him were mostly immigrants that had been here for over 10 years or their children that grew up here. Also, consider Bush in Texas... I rest my case. They are not your enemies unless you really really want them to be.
All you gotta do is look at the voting districts that border Mexico. Red districts they ain't. Any % vote toward Republicans, or consertative candidates, that is less than 50% is a net loss, no matter what you say. Besides, looking at illegals as potential voters is an insult to citizens of this nation, a violation of the law, and a reward for law breakers. California's huge budget deficit proves that the border jumpers are large net consumers of welfare and other "free" social services.
There are simple ways to have illegals "self-deport". The easiest is to make it impossible for them to work here through confiscation of Mexican consular cards and huge penalties for employers of illegals, which is already provided for in law and only needs to be enforced.
