The tables have turned and now the Obama campaign is going to the unions for a bailout of its own -- to help pay for the upcoming Democratic National Convention in Charlotte, NC:

President Barack Obama’s political advisers are pressing labor unions to contribute to the Democratic convention in September to cover a fundraising shortfall resulting from their self-imposed ban on corporate donations, according to two people familiar with the matter.

Democratic officials gave representatives of the major U.S. unions, including the AFL-CIO, the International Brotherhood of Teamsters and the United Auto Workers, a tour of the convention sites in Charlotte, North Carolina, April 23 in advance of a request for donations, according to the two people, who requested anonymity because they weren’t authorized to discuss internal strategy.

The three-day convention will culminate in Obama’s re- nomination in Bank of America Stadium on Sept. 6. So far, the host committee in Charlotte is roughly halfway to its $36.6 million goal.
