In Tx, the Lt Gov gets the power, the Gov gets the publicity. My guess is he is looking to move to a national scene, and the Gov set at is the way there for many.
That would be my guess.
But he has a serious problem now.
People just don’t like him, and rightfully so.
He is a nasty bit of work.
I’d look for Dewhurst to get into a position with some group whereby he
represents those wanting to move/expand in Texas. He knows the ins/outs
of the processes and could offer/grease the wheels. jmo.
