Washington (CNN) - They weren't on the ballot, but Bill Clinton and Sarah Palin are two of the biggest winners in this latest round of primaries.
The former president is being credited with helping Sen. Blanche Lincoln of Arkansas survive a Democratic Senate primary runoff Tuesday.
"President Clinton called me tonight when it was clear we were going to win and said, 'Blanche, you're the new Comeback Kid'," Lincoln said in an email to supporters.
Lincoln topped Arkansas Lt. Gov. Bill Halter 52 percent to 48 percent, after both candidates were forced into the runoff after neither broke the 50 percent mark in a three way primary contest last month.
