Just taking yer stats at face value with no links as back up:
Take the Cuban vote out and your Mex(and others) vote doesn't look tan bueno.
Your 50% of non-hispanic whites voting Dem is inaccurate in 2000 or otherwise Gore would be President. Nobody can win the presidency by getting 50% of the non-hispanic white vote and only 33% of the latino vote and only 10% of the black vote....it's a mathematical impossiblity. If the candidate gets only 50% of the peckerwood vote then he needs a majority of the minority vote obviously...to win.
BTW...I just looked it up. W got 54% of the PW vote ....his dad got 59%....and Reagan even better obviously.
I have little faith in the Mexican Campesino vote in my lifetime and besides have no desire to see the US become another departmento del Mexico culturally.
However, as a nod to latinos...Cubans in particular...without their vote and influence in Dade County...we would have lost.
By the way, I'm against illegal aliens.
