Two more reasons why Dewhurst decided to announce that he is running for reelection: (1) I am told by two sources that he called Hutchison to ask about her plans — was she going to resign her seat and if so, when — and he did not like the answer that he got. (2) Word reached him that Abbott has been saying around town that he was going to run for lieutenant governor. For once, Dewhurst didn’t dither around. His announcement made it much more problematic for Abbott to get in the race. As with KBH, he would have to explain why he is taking on a strong incumbent and dividing the party.
