Well, at least somebody understands the economics and politics of immigration (from National Journal):
Top Democratic leaders and activists see Hispanic migration as a long-term opportunity for the party. The arrival of additional immigrant workers is “bad for blue-collars,” Rep. Barney Frank, D-Mass., chairman of the House Financial Services Committee, told National Journal late last year. But immigrants can help elect Democratic majorities, and “if [a Democratic Congress] were to significantly strengthen unions, then you would offset the negative effect on the income of workers,” he said.
So, immigration screws low-skilled American workers, but helps more Democrats get elected, so they can pass socialist policies claiming to help workers. Barney Frank is, of course, correct, but why are Republicans helping him?
