Ted Cruz became a big cheese here because he took out David Dewhurst, the a Lieutenant Governor who had hoped to replace retiring Republican Denator Kay Bailey Hutchison. Dewhurst is no liberal, but he wasnt part of the Texas Republican Partys far right. Unfortunately for Dewhurst, 2012 was a year the Texas Republican Partys right wing was running strong and Dewhurst lost.
Unfortunately for Texas and the rest of the country, all too many qualified Texas citizens sat on their hands and didnt vote, all too many Texas voters had gotten it into their heads that they could only vote Republican, and Paul Sadler, admittedly the sort of sacrificial lamb the state Democratic Party nominated when the states Democratic PTBs think theyre going to lose, and Cruz won.
Admittedly Paul Sadler hadnt been active for several years before he got nominated, but I still believe that Texas and the USA as a whole would have been far better off if Texas voters had voted their self interests and sent Paul Sadler to the Senate in 2012.
IMO, Beto might be the first Democrat state-wide in ages who is rousing Democrats and real centrists from their decades-long lethargy that allowed the Republicans to misrule for so long.
