This interesting post appears at “Swing State Project.” It begins: “Background: Rep. Henry Cuellar is a Bush-worshipping ‘Democrat’ who is facing former Rep. Ciro Rodriguez – a bonafide Dem – in a primary on March 7th. There’s some speculation these days that Cuellar might try to switch parties, especially if he loses the primary – and indeed, I bet he wants to.” The post’s author concludes that Texas election law would prevent the switch. I have no idea if this is correct—I haven’t looked at the Texas law myself—but those who know something about Texas law should post a comment below.
