Actor George Clooney on Sunday said that President Barack Obama was likely to be re-elected, but cautioned liberals not to get cocky "because you will always lose."

In an interview with NBC's David Gregory, Clooney explained that the president has "always looked good to be re-elected."

"I happen to believe that Democrats are just very poor in general at explaining what it is when they accomplish something," the longtime activist remarked. "If I was a Republican, if Obama was a Republican, I would be selling all of the, you know, he saved the auto industry, he got Osama bin Laden, he passed the health care bill that nobody could pass. If that was a Republican issue, I would be able to sell his presidency as a very successful one. But Democrats are bad at that. We like to pick each other apart. That's our thing."

"The worst think you could do is in any way feel safe or cocky because you will always lose," he warned.

Clooney added that unlike his good friend Matt Damon, he was not disappointed in Obama "in the least."

"The issues that I believe in and the president that I voted for, I'm very proud of," the actor insisted.
