All kidding aside, perhaps yet another GOP debate isn't just a loopy rerun

Don’t look now, but another GOP presidential debate is gaining on us. In fact, it’s tonight on CNN direct from Mesa, Arizona.

You can view this seemingly endless string of debates basically three ways:

1. It’s reality television programming without the Kardashians or rich, spoiled housewives.

2. It’s Chinese torture — a prolonged death march until the Republicans get it right and finally fall in love with Mitt Romney.

3. It’s become the purest form of democracy we have and unlike previous campaigns, routinely shifts the balance of power.

Then again, perhaps it’s all of the above. Or at least has elements of all three.

Or course, all the hot air these debates generate is worsening global warming. Granted, no such condition exists for Republicans.
