Republican vice presidential candidates

Rob Portman

The pitch
Portman served as a former representative from Ohio, a key swing state. His former post as director of the Office of Management and Budget could also help McCain's image on domestic and economic issues.

The downside
Given President Bush's low approval ratings, McCain may not want to select someone who worked in the current administration.
