The Texas Secretary of State reports no Democrat filed for Court of Criminal Appeals Place 8.
Assuming some Green DID file for that spot, that's an obvious chance for the Party to get 5 percent in a statewide race and have automatic party ballot access in 2020. (I left a message on the newest post on Texas GP's Facebook page, and I've already tagged it on a Tweet.
The skinny on Petition driving? The party will need about 48,000 valid signatures. Petition drive time period is March 14-May 27, 2018. More details here and at links on that page.
I live in a highly conservative small town area. Plus, arguably, it wouldn't be ethical for me to run a petition drive.
That said, not only will I sign a petition, if asked, I'll tell people where they can go to sign, if somebody like Dallas Greens announces a date in advance.
