Why Not, Mr. President?

One more thought that kept occurring to me last night watching the debate...

Every time President Obama said "we need to do" this or "I'm going to do" that, I thought, "well, sir, what's been stopping you?  Why haven't you done that, if it's the obvious fix? If these are all things that are within your power to do, then why haven't you already done it?

Incumbents should not get too campaign on the things they want to do or should do.  They should be held accountable for the things they have (or haven't) done.
