You really think Santorum would help pick up PA, even though he lost re-election by 20 points to a mental incompetent? Not likely.
Rubio would be a good bet.
Cain could draw enough of the black vote to make a dent in Obama’s shrinking coalition.
Rubio would be a great bet to complete the destruction of the US constituion, especially article 2, section 1, clause 5, that specifies the natural born citizen (nbc) requirement for the position of the president and VP!
First you let soetoro/obama who is NOT a nbc to take the presidency, then you want Rubio who is NOT a nbc (he was born to non-US citizen parents!) to be the VP.
With people not having a clue that obama and Rubio are not nbc and not eligible to be pres or vp, the US constitution is doomed!
