Bill Clinton -- The Post-Porn Star Money Grab

Just hours after posing with two beautiful porn stars, Bill Clinton got on his knees -- and begged thousands of people for money ... all in the name of Barack Obama.

It's the 21st century way of soliciting campaign funds -- sending a desperately-worded email to masses of people across the country ... in this case, people who've subscribed to Barack Obama's newsletter.

He writes, "I've been in President Obama's shoes before -- less than six months to go before an election to let you finish what you started. It was tough enough back then, but this election is going to be tougher."

Bill goes on to ask for campaign donations -- and the pitch ... donating automatically enters you in a lottery to win a trip to NYC with Bill and POTUS, where you'll attend Obama's upcoming "Barack on Broadway" event (a total estimated retail value of $3,300). The MO is the same as the Clooney fundraiser -- only 2 people will win.
