But if we adjust the formulation to say: Hispanics have a strong tendency toward economic progressivism which trumps their social conservatism - for the first few generations.
Italians and Irish were solid Democrats as well for the first few generations.
The problem is that Bush and Rove probably aren't keen on waiting thirty or fifty or eighty years for the generational patterns to start favoring them.
Either way the short term prospects seem a bit bleak. Perhaps all Bush can do is push Hispanic apointments, aggressively politic in hispanic communities and push local hispanic candidates and count yourself lucky to get 40% of the hispanic vote - and crack down on immigration.
