I used to teach Texas state government and the basic premise of my lectures to students: Texas is anti-government. So the apparent lack of voter interest in the governor's race is not surprising. Neither candidate has addressed large political rallies anywhere in the state thus far, at least that I know of. Maybe it's because the voters are so apathetic they wouldn't attend the rallies if there were any scheduled.
But will there be televised debates? If you recall, in 2010 Democratic candidate Bill White debated an empty chair at the TCC South Campus...it ended up being a one-on-one interview of White by Bobby Ray Sanders of the Star-Telegram. Of course no incumbent wants to debate, least of all Rick Perry running for his last term. But this is an open-seat election this year and there's no reason why either candidate should bow out of a debate. We need to know better the candidate's positions on health, education, etc., and debating is one of the most effective ways of achieving that information. I hope we get the debates in late October.
