Not saying President Obama should be jittery about Andrea Mitchell jumping the White House fence anytime soon. Even so, the prez would have reason to be concerned if such a generally staunch ally as Andrea openly laughed at his lack of credibility.

View the video and judge for yourself. On today's Morning Joe, Republican Rep. Matt Salmon predicted that President Obama would send ground troops into Syria sometime after the November elections. Andrea asked "despite the president's promises?" To which Salmon replied "he also promised if you like your insurance you can keep it. Come on." Much mirth and hilarity on the set ensued. Andrea can be seen laughing heartily. Was she doing so at Salmon for spouting GOP talking points, or was she laughing at President Obama's lack of credibility?

Perhaps it was just a light moment. But such open mocking of the credibility of the President of the United States is a serious matter. And imagine being a Dem candidate in a tough race watching this today. Now imagine your blood running cold.
