Bush only mentioned ONCE(?) in the Republican debate?

I knew the Republicans were shying away from George Bush, but doing a quick search on the transcript, I found only one time that any of the candidates referred to the current President by name.

ONE TIME in an hour and a half debate.

He's the sitting two term president for their party and only one mention of his name by 10 Republican candidates for president.

If you can't say something nice......?
