My initial thought is: These two probably don't.
Bell endorses Jones. Chris Moran, Chron.com
Rodriguez, Harris and Stipeche for HISD board. The Apple Dumpling Gang, Chron.com
Let's start with the easy one.....
I'm not sure the candidate who couldn't out draw a corpse is really someone who I would rely on to bring the vote. It's a testament to Kelly Cripe's savvy as a PR flack that she's wise enough to not use it in a mailer. Chris Bell? Meh.
At least, that's what most people would say, but Bell is a fave rave with the local InterLeft and Chron.com. Because of this, his endorsements are constantly paraded out in support of favorites that are probably going to win (comfortably) anyway. The effect of this is that Bell's self-delusion of popularity (Wow! My endorsement really put THAT candidate over the top!) is maintained and he's still mentioned as a serious Democratic candidate for almost any office that opens up for which he's eligible.
Even worse, is the Apple Dumpling Gang's endorsement.
First: No one pays attention to them any longer, and second, they obviously don't place the same weight on a Prog politician's cronyism as they do on a Republican candidate's cronyism. Besides that, when your definition of "qualified" seems too be more closely tied to idealism (in this case: Prog) than to actual qualifications you run the risk of losing credibility. For many years now the Apple Dumpling Gang has had zero.
If you haven't heard the phrase "post normal science" I encourage you to go look it up. Not only is it anti-science, but it's also the foundation for much of the human-driven climate change movement. What we're getting close to in Houston is "post normal politics". Where key players are recasting basic facts in a more favorable light to ensure a desired result.
I'd say you should think this is a problem no matter what side of the aisle you're on, but we know from the recent past that, at least, one side has no problem with hi-jacking civil discourse to advance something that's destined to fail. (Yet which has been sold to them as a panacea all facts to the contrary)
