Can Debra Medina throw a monkey wrench into the race for comptroller? She doesn’t have the money to compete with the two leading candidates, Hegar and Hilderbran, but she has residual name I.D. and a loyal following left over from her 2010 race for governor. (See my colleague Erica Grieder’s interview with her from December.) At the very least, Medina could throw the race into a runoff. Who votes in runoffs? The most involved voters: in short, the tea party – Medina’s core constituency.
