Republican vice presidential candidates

Lindsey Graham

The pitch
South Carolina Senator Graham, who recently accompanied McCain on a trip to Europe and the Middle East, is a good friend of the Arizona senator and the two agree on numerous policies, including their opposition to abuse of terror suspect detainees.

The downside
The former military lawyer Graham has similar strengths to McCain, and McCain may seek someone less like himself. Additionally, South Carolina is traditionally a GOP stronghold, and McCain may want a swing state candidate.
