DeLay will run hard and going after the Dem candidate, like his political life depends on it. Last time, DeLay was forced to spend money, but next time, he knows money won't be enough.
Morrison was all set to run and blogging for support mid week and at the end of the week a couple of new blogs hit the internet, that are Democrat and they want someone who is not Morrison. Besides the fact that Morrison leans conservative and some Dems in the 22nd want a progressive candidate, they brought up somethings that would be used against Morrison next year, by DeLay. That might have cause Morrison to have second thoughts.
