Libertarian Railroad Commissioner nominee Mark Miller picked up several endorsements from Texas newspapers, including the Houston Chronicle. Miller is well on his way to grabbing the Holy Grail for minor-party candidates in Texas: 5% of the vote in a race with both major parties running. If his current figure of 5.22% holds, he will guarantee access to the Texas ballot for the Libertarian Party in 2018.
Wayne Christian will keep that seat in Republican hands, handily fending off challenges from Miller, Green nominee Martina Salinas, and Democrat Grady Yarbrough. Republicans are winning all the statewide races in Texas by the usual margins: about 14 percentage points, although Trump's lead in the state is less than 10.
Nonetheless, Miller's showing is a victory of sorts for minor parties in general. If the Libertarians can do it, then so can the Greens. Salinas herself is up over 3% in that same race, improving over her 2% finish in 2014.
