A "win" is relative. In Texas, in order for people to run for any partisan race: Justice of the Peace and other county level offices, state legislature, statewide office like Supreme Court, Criminal Court of Appeals, all the way up to Governor and President, a party has to have ballot access. Obtaining ballot access is no easy feat. TX is the fifth most difficult ballot line.
The easiest way is to maintain ballot access once a party obtains it as we did again in 2010. Parties do this by running statewide candidates. Therefore, a "win" is 5% in any statewide race. See: "How to strategically help the Green Party get 5% for ballot access in 2018".
If a party doesn't get 5% in a statewide race, then two years later, they must spend ~$200,000 to collect signatures of registered voters who didn't vote in a primary, or sign the petition of another party, in 75 days - one must collect about 50% more signatures than are required to account for people who have been removed from rolls, or never had their registrations entered by the DMV (a big problem in TX), or never actually registered, but say they are. So it amounts to approximately 75,000 signatures in 75 days. That's 1000 signatures a day.
The hurdles to running for Justice of the Peace, County Commissioner, Tax Assessor, State Legislature, etc. should not be this high.
Independent candidates also have high hurdles, and in some cases it is even easier to get a party on the ballot than an Independent, e.g. President.
So if you have great Green local candidates in your area, we hope you will elect them and vote for Statewide candidates so they have the opportunity to run for reelection, and others like them can run at all.
