He hasn't officially announced anything, but it's safe to scratch Rep. David Swinford, R-Dumas, off the list of possible candidates for Texas agriculture commissioner. He's been letting agriculture groups know he won't make the race next year.Swinford was one of several people mentioned as possible replacements for the current head of the agency, Susan Combs. She's readying a bid for comptroller of public accounts. Initially, she said she was getting ready to run on the assumption that Comptroller Carole Keeton Strayhorn would be running for another office. But Strayhorn's battles with her fellow Republicans in the Texas Capitol have raised temperatures to the point where Combs would probably muster some support even if the incumbent tries to stay put. Sen. Todd Staples, R-Palestine, wants to run for agriculture commissioner if it opens up; that's not official, but he's doing all the things you'd do to set up a run, talking to potential supporters, working on high profile legislation, and importantly, letting potential competitors know he'll be one of the obstacles they face. Swinford told us he thinks he'd be the best guy for the job and that he would announce his plans one way or another to his constituents in the Panhandle. But in conversations with various agriculture groups and their representatives, he's saying he can do more for farmers and ranchers in his present position in the House, where he chairs the important State Affairs Committee, and where he's currently one of the House negotiators on the tax bill. Combs is holding organizational meetings later this month (though she and other current officeholders are barred from collecting contributions or commitments while the Legislature is in session). Strayhorn has indicated, vaguely and through aides and friends, that she'll announce her intentions in early summer.
