Pennsylvania Gov. Ed Rendell says discouraged liberals need to “get over it” and support the Democratic Party, before they regret it.

“This isn’t about President [Barack] Obama,” Rendell said on MSNBC’s “Last Word” Monday night. “It’s about whether the Democratic Party, not perfect, but certainly bent on trying to preserve theories in government and progressive practices, is going to be in charge of the Congress or the Republican Party. And it’s not the Republican Party of old. This is a scary Republican Party.”

Of conflicts the left has had with Obama, Rendell said, “We ought to get over it.”

“If we’ve got some issues with President Obama, save them for another day,” he said.

…“If the left or moderate wing of our party wants to challenge somebody, I think it’s fair game,” he said. “But that’s all over.

“We need to all of us get over it, get out to vote, even if there’s not a wildly enthusiastic vote,” Rendell added. “There’s an old maxim on politics, a tepid vote counts exactly the same as a wildly enthusiastic vote. Let’s keep the Congress.”
