"Pick any other Republican in the country. He is the worst Republican in the country to put up against Barack Obama."
Santorum made the statement in Racine, Wisconsin, quoted here.
How about John McCain, for example? He actually lost against Barack Obama, as I recall. Wouldn't he be a worse candidate today than Romney?
Or how about Mark Foley?
Or Duke Cunningham?
There must be scads of Republicans who would be worse candidates than Mitt Romney, but Rick Santorum can't seem to muster the proper perspective to imagine who they might be or where Mitt Romney fits in the scheme of things Republican.
Rick Santorum has proven before that he exercises bad judgment from time to time, say by encouraging Democrats to interfere in Republican primaries, or by writing-off mainline Protestants, not just from electoral politics but from Christianity itself. This is yet one more example of an ill-considered opinion best left unexpressed.
And those sorts of things make him an incendiary candidate who cannot win against Barack Obama.
I'd say that makes him a worse candidate than Mitt Romney.
