Bush senior endorses . . .?

Factual Questions

No party political stuff. Just a couple of simple questions.

I’ve been watching BBC & CNN in the UK over the past week. Clinton, Arnie and loads of celebs have been out endorsing their favourite. Even Reagan Jr., IIRC, was endorsing. I haven’t seen Bush Sr.

So has Bush Sr. been out supporting his son? If not, why not? Has it been commented on in the States?

(He’s not dead, is he? That’d be embarrassing.)
