On February 28, Texas Representative Phil King (R-Weathersford) introduced HB 1661. It would change the vote test for a party to remain on the ballot from 5% for any statewide office (or 2% for Governor), to 10% for any statewide office. King had no Democratic opponent in 2006, but he did have a Libertarian who polled 19.6% of the vote against King. Apparently King would have preferred an election in which he had no opponent at all.
The median vote test for a party to remain on the ballot, in the 50 states, is 2%.
