The Republicans haven't wasted any time on attacking the presumptive Democratic nominee Barack Obama.

This new ad pits Obama's most recent rivals in the Democratic field against him on "experience."

Hillary Clinton is basically the star of the video, but John Edwards and Bill Clinton also pop up as well.

If Obama thought the Clintons were hard on him, wait until he gets a dose of John McCain and the Republicans.

Meanwhile, the Clinton campaign says there has been no talk between Hillary and Obama about her joining his ticket in November. Obama continues to praise Clinton fueling fire to the speculation.
