Texas has four ballot-qualified parties: Republican, Democratic, Libertarian, Green. Parties remain on the ballot by either polling 2% for Governor, or 5% for any statewide race. In 2014, there are three statewide partisan races in which no Democrat is running. This makes it virtually certain that both the Libertarian Party and the Green Party will poll over 5% for those races, and thus will be on the ballot in 2016.
The three statewide offices with no Democratic candidates this year are State Supreme Court seat 8; Court of Criminal Appeals seat 4; and Court of Criminal Appeals seat 9.
On another Texas topic, January 2, 2014, was the deadline for any unqualified party to tell the state if it intends to petition in 2014. The Texas Secretary of State’s office says the information as to whether any unqualified party filed that notice by the deadline won’t be known until Monday, January 6.
