So what are you going to do come november?
Remember this was being pushed before Bush was elected the first time - it's died down precisely because with the republicans holding all the cards it wasn't going anywhere.
As for the republicans kowtowing to the latinos, the reason you're seeing that is because the republicans think that the latino vote is in play whereas the black vote is not.
Having said all this - I'm as disgusted as you are by the spineless people we put in office. The question we're up against is this - are we at a point where we cut our noses to spite our faces?
I believe we are at the point where the vote only makes people feel better about what's going on in America, but that it doesn't really matter much who we vote for. Look at the facts: Republicans hold the House, the Senate, the SCOTUS, the governorships and the White House. This tells me, clearly, that conservatives have indeed banded together and used the power of our vote to change things around. YET, we are becoming more and more liberalized and globalized every year in spite of this.
I would, however, vote for any man who has real spine and would actually come right out and say, "a vote for me is a strong vote against illegal immigration; I will deport those that are here already and I will help see to it that a wall is built on our southern border". In other words, I'd vote for a guy like Tancredo any time because it's clear he is willing to risk his political popularity for the best interests of America. But based on what I see today, the two parties are largely the same. Bush is one of the most liberal Presidents of my lifetime; I actually consider JFK to have been more 'conservative' than "W" is, and that's not saying much.
