Sen. Hillary Rodham Clinton plans to campaign for Barack Obama in Nevada and Florida this month, events expected to be her first solo campaign appearances on Obama’s behalf since she lost the Democratic nomination contest.

The Obama campaign said Tuesday that Clinton will host rallies and voter registration events this Friday in Las Vegas, Nevada, and again in South Florida on Aug. 21.

In June, Clinton and Obama appeared together in Unity, N.H., in a symbolic event to push for party unity after their long and often bitter primary battle. Both also have been helping each other raise money, in Clinton’s case to retire her own hefty campaign debt.
