Two weeks after his loss to Gov. Rick Perry, the former Houston Mayor said he will not run for the U.S. Senate in 2012. Prior to entering the gubernatorial race last year, White had sought the senate seat many had expected Sen. Kay Bailey Hutchison to vacate. White additionally said he had no plans to run for office in 2014 either and was evaluating future business plans.
The announcement can hardly be described as surprising, though the timing of it may be earlier than many had expected. Former Texas Comptroller John Sharp has said he plans to run for the Senate in 2012 (although his website currently offers advice on how to find "the best male enhancement pills").
The Republican side will likely be crowded, as Railroad Commissioners Elizabeth Ames Jones and Michael Williams along with former Secretary of State Roger Williams and State Sen. Florence Shapiro were all planning on running in what they thought would be a special election. Whether they all ultimately run is unknown, but it seems unlikely.
Lt. Gov. David Dewhurst could be the Republican frontrunner, but his decision will not come until after the upcoming legislative session. Depending on the political climate, Democrats could see a legislator, or perhaps someone we have not even heard of yet, jump in after the legislature adjourns in May.
Update: As Robert points out in the comments, Hutchison has become well known for saying one thing and doing another when it comes to her future in the Senate. While I still expect her not to run again, Robert is right that given her history it is far from a sure thing. However, if she does choose to run again, Hutchison could find herself as a target for a challenge from the right in the Republican Primary.
