WASHINGTON - Democratic presidential candidate Barack Obama will campaign for the first time alongside former president Bill Clinton at a rally next week in Orlando, Fla.

Obama campaign spokeswoman Jen Psaki said the two will appear together Wednesday in the perennial battleground state.

Orlando sits in an important swing part of the state, where Clinton could help Obama among the white working-class voters who so strongly supported his wife.

Bill Clinton was cool toward Obama following the bruising nomination battle between Obama and Clinton's wife, Senator Hillary Clinton.

However, any lingering animosity was put aside when both Clintons gave rousing endorsements of Obama at the Democratic National Convention in August.

Since then, Bill Clinton has campaigned for Obama on his own, but the two have not appeared together at such an event.
