Take a circle, add a jerk and what do you get?

One answer is another GOP presidential debate. Number 20 was in Mesa, Arizona, for those keeping score at home.

There was no big knock out, or even a knock down. In fact, the best any candidate can say is . . .

Front runners, Rick 'Anyone but Mitt' Santorum and Mitt 'I Really Like Michigan Trees' Romney tried to hang the other guy onto someone else. Santorum raised the specter of the president, and Romney raised the specter of, well, former Pennsylvania senator Arlen Specter.

Santorum: 'It would be a very difficult task for someone who had the model for Obama care, the biggest issue in this race for government control of your lives, to be the nominee of our party, you would take that issue completely off.'

Romney: 'If we had said `no` to Arlen Specter, we would not have Obama Care. So don't look at me. Take a look in the mirror.'

Does this sound like playground taunting to anyone else ('I`m rubber, you`re glue!' 'Oh, yeah?')

The highlight of the night may have been when each candidate had to describe himself in one word.

Lake Jackson congressman Ron Paul: 'Consistent'.

Former Speaker of the House Newt Gingrich: 'Cheerful'.

Santorum: 'Courage' (which we should note is not an adjective).

Romney: 'Resolute'.

Arizona and Michigan hold contests next week, then ten states make up Super Tuesday on March 6.

And just think; we have eight long months of this before the November general elections.
