That's the thing you don't understand about the Houston Chronicle. They don't do real dirt digging. They do political smears and character assassinations to promote a left wing agenda. Their hatred of Tom DeLay is legendary in the Houston area. They've run an editorial condemning him every two or three weeks for the last three years. None of it has any substance to it. None of it contains any real dirt on DeLay. It's all the same old story - "Tom DeLay's a right wing conservative christian extremist who hates light rail and progress." They've been alleging that it has to do with some tie he has to highway contracters for years, but not once have they ever given any specifics. It's all propaganda smear attacks.
If its superficial, then its easy to refute.
If there's any substance, let 'em go at it.
There's plenty of opportunity for corruption on any construction project of this nature,
it doesn't much matter whether its highway or light-rail,
both require awarding of construction contracts,
both require land acquisition, (perhaps from "speculators" with inside connections)
Let 'em report what they have to report, judge the validity of the dirt after it's published.
