…the 20th and possibly final GOP TV debate

Amazingly there have been nineteen separate TV debates in the fight for the GOP nomination. Tonight’s event, being staged near Phoenix in Arizona, is the twentieth and will almost certainly see Rick Santorum coming under close scrutiny. In all the previous events he’s never been centre stage and it will be interesting wathching how he performs and how the other contenders react to him.

A lot of this is not about the words that are exchanged but the overall impression that is given. Body language is as important as what is said.

All but Gingrich have vetoed other debates planned for March and this could be the last.

It’s on CNN and starts at 0100 GMT.
