Impeachment

Ferguson v. Maddox, the Pa Ferguson Texas case from the 1920's, and the Impeachment After Leaving Office article that discusses it. Ferguson resigned after his impeachment but before his Senate trial. He was impeached after he started a big fight with the President of the University of Texas. In 1924 he wanted to run again, but his wife, Ma Ferguson, ran in his place because the Texas Supreme Court ruled that his Senate trial was valid and disqualified him from office. She ran against the KKK's candidate and won.
