The Texas GOP can’t even find a Democrat primary challenger for Queen Sheila Jackson Lee’s seat in the Houston Heights (an older neighborhood with costly properties favored by upper middle class and upper class yuppies). They may be liberal Democrats but it’s not like Sheila gets challenged to debates every election.
If you want to waste time and $$$, run a conservative in that district. It's a lot more than the Heights...it also includes the Benz area.
Craig Washington was the congressman from that district until he was killed in a plane crash. He was constantly in the news for breaking one law or another and always won and would be there today if his plane hadn't gone down.
But... you get the point,
