Ridge for VP?

CNN reports that former Pennsylvania Governor and head of the Department of Homeland Security Tom Ridge would consider being a VP if asked by the McCain campaign. The article focuses on Ridge's pro-choice stance as the primary stumbling block with GOP voters. But my thoughts more run along the lines of: "wasn't he a catastrophe as head of the DHS?" Now, this could be mistaken. I could be confusing him with other Bush administration appointees (incompetence is a pretty widely shared character trait, so it's a solid bet). I could be over-estimating the degree to which incompetence is a bar to GOP voters (likely). But still, it strikes me as not the wisest choice available to McCain (personally, I think Minnesota Governor Tim Pawlenty is the best choice -- I'm not even sure what his downside is supposed to be).
