In an interview with Fox News today, MPAA chairman Chris Dodd warned that the entertainment industry could withhold contributions from President Obama and other politicians who fail to support anti-piracy legislation.

“Don’t make the false assumption that just because we did it in years past that we are going to do it this year,” said Dodd.

He added,”Candidly, those who count on quote ‘Hollywood’ for support need to understand that this industry is watching very carefully who’s going to stand up for them when their job is at stake. Don’t ask me to write a check for you when you think your job is at risk and then don’t pay any attention to me when my job is at stake.”

There have been grumblings among studio chiefs that they would withhold support for Obama’s re-election, but it is unclear whether they will actually follow through with it. Dodd’s words are the first public indication that industry leaders are using campaign contributions as a pressure point, after dismay over the White House statement over the weekend that was critical of anti-piracy legislation.

Meanwhile, Vice President Joseph Biden was scheduled to arrive in Los Angeles this evening for a dinner with business leaders.  He also has fundraisers planned during his visit, but a source says that he is not going to be trying to work out a deal on SOPA with studio heads.

Those expected at the dinner include Montage Hotels’ Alan Fuertman, City National’s Russell Goldsmith, Masimo Corp.’s Joe Kiani, AEG’s Tim Leiweke, CODA’s Phil Murtaugh, Mattel’s Bryan Stockton and former U.S. Ambassador Robert “Bob” Tuttle.
