Mother Jones has a great profile of the race between Ellen Cohen and Martha Wong going on in Houston right now. It's a good article and you should read the whole thing, but this graf pretty much says it all about Martha Wong:
As Wong climbed the rungs of power at the state Capitol, however, she seemed to cast aside many groups that define her district. For example, environmentalists have been drawing attention to extraordinarily high ozone levels in the part of Houston that Wong represents, yet Wong voted against five separate clean air measures. Schools are a big issue in the highly educated district, yet Wong, a former elementary school principal, opposed a bipartisan proposal to raise teacher salaries. Wong acknowledges that voters in her district are independent-minded yet in an interview couldn’t cite a single instance in which she’d voted against her party.
No amount of red tape is going to cover up Martha Wong's record.
