Rob Portman, a veteran of President George W. Bush's White House and Cabinet, easily won the Ohio GOP primary and has a 9-1 fundraising advantage over his Democratic Senate opponent, Lee Fisher. Still, this is a very tight race and is considered the Democrats' best hope to win an open seat the GOP holds now. Palin's endorsement of Portman shows her willingness to back an establishment candidate like him instead of always embracing tea party-backed, anti-establishment contenders.
