White House canceled Obama's political calendar today

After this morning's CDC presser, I heard radio news report Obama canceled his "political event calendar" today to deal with the Ebola crisis.

Now I see this:

Obama had been slated to visit Union, New Jersey, for a Democratic Senatorial Campaign Committee fundraiser before traveling to Bridgeport, Connecticut, for a campaign rally with Gov. Dannel Malloy. Earnest said both events will be rescheduled before Election Day. 

So, what gives?

Are Dems telling Obama to stay away?

Do internal White House polls show his numbers in complete collapse?

Third possibility: White House expects significant bad turn of events near term, and is attempting to rehab Mr. Obama's image to some extent before the next wave piles on.

It's not like Obama to ditch a pep rally. He seems to live for that kind of stuff.

What's being said in today's White House Ebola meeting to make Obama think it's worth  blowing off a fundraiser?

BTW, this is the second scheduling move that may suggest unfolding Ebola events are far more serious than politicians or bureaucrats are letting on. The first was that suspiciously timed late Friday public briefing on October 3rd.
