About 32% of Hispanic voters are Protestant, they voted 56% for Bush in 2004, Catholic Hispanics gave Bush 33% of their vote in 2004, exactly the same as they did in 2000.
In the 2008 election republicans only got 22% of the Hispanic Catholic vote but they still received 48% of the Protestant Hispanic vote.
While you are claiming that 32% of Hispanics are Protestant, I am quite skeptical and I was using the Mexican vote figures and not the Hispanic figures generally. The other major Hispanic groups are Puerto Ricans who tend to be overwhelmingly Demonrat and the much smaller Cuban population that is still heavily Republican but not as much as previously.
I have no interest whatsoever in getting involved in a Catholic vs. Protestant urination contest here. I also claim very little knowledge of Hispanic Protestants of any stripe. If 48% voted Republican, good for them and may they be ever more Republican than they already are. I can tell you that the GOP is suiciding with the Mexican Catholic vote and that is borne out by all voting statistics in recent elections and trends among them. The high percentage of Hispanics among Catholics (most of them by far Mexican) threatens the GOP among Catholics generally since attacks on some of us are often regarded, right or wrong, as attacks on all of us.
Again, the Demonrats, in spite of their all out support for baby-killing and for sexual perversions, play the game of politics infinitely better than does the largely clueless GOP.
