The Oklahoma Speaker, Dan Draper, was convicted in 1983 for election tampering. He was trying to help his father win a seat in the Oklahoma legislature.
The Tulsa World reported;
Then-House Speaker Dan Draper’s troubles began in 1983. He and House Majority Floor Leader Joe Fitzgibbon initially were convicted of mail fraud and conspiracy charges for allegedly fixing absentee ballots to help Draper’s father in an unsuccessful race for a House seat. Draper and Fitzgibbon later won new trials (in 1985), but a federal judge dismissed the charges at the behest of U.S. Attorney Roger Hilfiger. Muskogee Democrat Jim Barker became the new speaker thanks to Draper’s troubles.
Draper was further convicted in 1984. the Tulsa World said;
Dan Draper ended up in more trouble. He was arrested in February when a police officer found him slumped over the wheel of his car. He pleaded no contest to actual physical control while intoxicated, a charge later amended to a lesser offense after a year of probation.
