Rick Santorum says his presidential campaign rival Mitt Romney is "the worst Republican in the country to put up against Barack Obama."
Santorum on Sunday told voters in Wisconsin that Romney is "uniquely disqualified" to be the GOP's presidential pick and urged his supporters to stand with him even as he faces an increasingly improbable pathway to the nomination. Santorum says "the race isn't over until the people of Wisconsin sing."
Santorum says front-runner Romney wrote the blueprint for Democrats' national health care law and would have a terrible showing in a head-to-head debate on the issue. Santorum says Romney is an inconsistent figure who cannot be trusted and is calling him an "Etch-A-Sketch candidate" whose positions change as easily as pictures on the children's toy.
