On Sunday, Gov. Jan Brewer endorsed Mitt Romney for President.  Romney has been falling steadily in the polls in both Michigan and Arizona, which vote tonight.

Romney’s campaign has become a disaster.  He lost Iowa.  He lost Minnesota.  Although the Maine GOP initially claimed that he had won, it is increasingly looking as though Ron Paul actually beat Mitt Romney there as well.

While it had been long believed that Mitt Romney was the inevitable choice for the GOP, things have been bleak for the Romney campaign.  However, the endorsement of Jan Brewer may go a long way to helping Romney scrape a win in Arizona.

But even if he DOES win Arizona, the tone of the Romney campaign has changed.  Santorum is in in the lead, Ron Paul is energized and his supporters are motivated, and Newt Gingrich is still hanging around, waiting until Romney’s perceived lead is completely shattered in order to jump in and grab the contest by the horns.

So this latest endorsement is good news for Romney, but it’s not enough.  The only good news that he really needs to hear is that he has won both Michigan and Arizona, and done so handily.

I doubt he’ll be getting that message tonight.
