Sen. John McCain (R-Ari.), a prominent Romney backer, on Tuesday laughingly addressed the Obama campaign’s new ad featuring Big Bird, joking that he differs from the GOP candidate over the “Sesame Street” star.

“Big Bird I guess is a fun thing to run on,” McCain said on NBC’s The Today Show. “I love Big Bird. I’m for an earmark for Big Bird.”

During his Senate career, McCain has been a staunch opponent of earmarks in legislation.

The Obama campaign on Tuesday unveiled a new television ad mocking GOP candidate Mitt Romney for his calls to cut federal funding for PBS, which he cited as an example of a measure which could help reduce the deficit.
