The DA is Ronnie Earl a Democrat political hack. He went after Kay Bailey-Hutchinson a few years back. the process played out over about 10 months, cost millions of dollars and the jury came back with not guilty in about 20 minutes.
This is a pure political ploy to neutralize Delay for the mid-term elections. Ronnie Earl couldn't get a conviction if his life depended on it. Interestingly his job never does.
So basically he's their Larry Klayman.
Thanks for the information and the context.
