Whites and blacks have been pretty stable in their feelings towards the Democrats this year. But can someone explain to me why Latino support for Democrats is plummeting during a year when Republicans have been falling all over themselves to back Arizona-style crackdown laws? I don't get it. Gallup's explanation, that Latinos are upset with the Democrats for not passing immigration reform, doesn't quite ring true to me. The passage of the Arizona initiative just has to be a higher salience change than the national government's failure to act.
