You can give up on buying a Governor in Texas, it just isn't going to happen. It was possible a long while back, but not now.
In Harris County, it was very difficult to find a Judge to buy at any price, but it that's probably going to change. The Democrats won all judicial races in November, so the market will pick up. I have no idea what the price will be, but the problem is the length of ownership. They are so much in demand that there's always someone who is going to offer a higher price. Judges just don't stay "bought" these days.
Best of luck.
