Republican guest Kate Obenshain was so ridiculously off-base last night that Bill O’Reilly slapped her down so that Democrat James Carville didn’t have to.

Bill O’Reilly is hardly an Obama supporter or an apologist for the Democrats. But he doesn’t suffer fools gladly and there is just no other way to describe Obenshain’s argument as foolish. That is, if shrewish, mean spirited and dishonest is just a little too blunt.

In a wider-ranging discussion about President Obama and the failure of Congress to deal with the border crisis, O’Reilly addressed Obenshain: "You’ve got to admit… that we have two parties who are both supposed to be working together for the good of the people. Alright? Not to destroy one another. That’s not our system. OK, but now, nothing can get done."

Obenshain showed none of the personal responsibility Republicans are always demanding from others. She blamed Obama. “You know what, Bill? Since Day One this president has been determined to vilify and demonize the other side. He wants to shut down debate –"

Now, that’s rich. Because even before Day One of Obama’s presidency, Obenshain was on Fox vilifying and demonizing him. For example,

on June 20, 2008, Obenshain said Obama “wants to grant Constitutional rights to terrrorists.”  In October, 2007, Obenshain deliberately impugned Obama’s patriotism for not wearing a flag pin on his lapel. “It matters to our troops who are in harm’s way. …People already have some serious questions about Barack Obama on foreign policy,” she said.

O’Reilly interrupted what he knew was a load of BS. He asked about Republicans, “Shouldn’t they rise above, the other side rise above it and put good stuff in?”

No, Obenshain just wanted to stay on the attack – and then blame the Democrats for it. “You know who’s talking about impeachment, James?” she asked. “It’s not the conservatives and it’s not the Republicans. It is the White House, it’s Michelle Obama …The White House is all over it. …It’s used to divide America… It’s used to divide Americans and score political points.”

Obenshain has a hell of a nerve complaining about anyone else being divisive. In addition to the examples of her divisiveness above, she is also the woman who said, “Hillary Clinton thinks that she is God’s gift to the country.”

She’s also got a hell of a nerve saying that conservatives and Republicans are not talking about impeachment. I recently drew up an informal list of impeachment talk just on Fox News that has been going on almost since Day One of Obama’s presidency.

Even O’Reilly ran out of patience with Obenshain. “Kate, there’s plenty of hate on both sides,” he said.

“No, there’s not, actually,” Obenshain insisted. “There are policy differences on the conservative side. That’s the difference.”

O’Reilly told her, “Kate, if you don’t know there’s plenty of hate on both sides, I can’t help you.”

“Bill, wake up,” she insisted.

“I’m awake,” he said.

Indeed he was – and he was 100% correct in this exchange.
