I mean they literally have a publicly available plan... So as long as that's the plan then yes, I will vote for the party with the best chance of defeating them. If that were green, I'd vote green, if that were libertarian I'd begrudgingly vote libertarian. Currently it's democrats though.
We have to push incumbents towards legislation that benefits 3rd party options to see any real headway in the 3rd party category. Until that's in place 3rd party can never succeed on a national level. Again, looking at statistics, it's just not possible until law favors multiple party conditions.
