It’s widely known that John McCain has a very bad temper. For the GOP, this is going to be a big problem between now and November.

According to Jonathan Martin, who closely monitors the GOP for the Politico, the general election campaign is already getting to McCain — and it’s barely just begun. Martin’s article describes McCain’s growing frustration with the media (yes, the media which once fawned all over him) and McCain’s use of “stinging attacks” on Obama. But, the best line appears under McCain’s photo:

It’s not clear that John McCain can contain his temper while battling both Barack Obama and the press.

Yes, the GOP has a big problem with its candidate.

This means only one thing: The Republican attack machine is going to be in overdrive and get more ugly than ever. As Jed reports, the smear attack against Obama have already started on McCain’s website. Now, this election should be about the important issues facing our nation. It should be. But, since every issue across the spectrum works against McCain and the Republicans, we better be prepared for a full-scale assault of lies and fear-mongering.

This time, we’re prepared to fight back — hard. There’s plenty of material available on John McCain and his not so perfect past that most Americans don’t know yet — but will. (And, yes, that includes Cindy McCain, too.)

In the meantime, it does seem only a matter of time before the American people see for themselves just how nasty and unhinged McCain is. He just can’t control himself.
