I think Sheila Jackson Lee can defeat a republican.
If it's her vs. Whitmire, she will have a more difficult time.
Apparently, Buzbee is considering getting in. He says he thinks he is the only one that can defeat SJL. When in actuality, he would help her win.
I expect that she would consolidate that Black vote. Whitmire is hoping to win the conservative white vote, like Rick Caruso and Paul Vallas. He's been endorsed by Tilman Fertitta, Dan Huberty, Greg Travis, Mattress Mac, the Houston Police Officer's Union, as well as some mainstream Democrats.
I see most party-line republicans having a difficult time voting for a Democrat. I find it hard to believe that the Harris County GOP will endorse Whitmire. I think they run their own person and hand it to SJL.
Despite persistent rumors, I will not, at this time any way, be entering the Houston mayoral race.
