I don't see the point of bringing up this as a ploy to win votes. What politician do you know of that doesn't do that? Forget politician, what human being do you know that wouldn't do something that they know could benefit them in someway? He is, however, not jumping on something he doesn't genuinely support. He campaigned on things like this. So the timing is political... so what? That's how the game goes. Show me a politician who doesn't do this then I'll care.
lorettahknox, I agree with you about how people react to President Obama, but disagree with the rest. Yes, arriving in this country illegally is a crime but it's not the same as crimes committed by people who prey on others as you seem to be defining it. These people come here to take care of themselves and their families because they can't do it in their country. They work for crumbs and do a lot of jobs that we just wouldn't do (we say we'd do it it but that's only because our bluff is probably not going to be called). You have politicians screaming about tougher immigration policy and strengthening our borders in public, while having an illegal as a worker in their homes. Bottom line, they keep a lot of people in business for cheap, so sending them all home is just not realistic. The bottom will drop out of some industries.
I'm not saying we should have an open border policy. We should strengthen our borders and have tougher policy (cracking down on businesses hiring illegals mainly... no work, no reason to come over) but for the many that are here and have been here for a long time, we have to be realistic and kids shouldn't have to pay for their parents choices.
