If Santorum gets the GOP nomination, that is spectacular news for the Democrats. The Democrat victory would be by over 15% compared to 3% if Romney would be the candidate.

How many Hispanics and Black voters would vote for Santorum? Hardly any is the answer. He is basically bigoted as shown in this link where he targets blacks as recepients of aid and no one else. Santorum targets blacks in entitlement reform - Political Hotsheet - CBS News

I say Santorum should be the candidate. It would provide an even easier victory for President Obama.
