Our electoral system is inherently biased against 3rd party candidates due to the spoiler effect of first past the post voting. The only solution is election reform that regulates election finances, a switch to approval/STAR voting, and regulation on political ads.
I can recommend against enders. I have two friends with them, and one myself. Between the 3 of us none of them are currently working, and its been like this since i found out all 3 of us had 3d printers. Keeping them working is like pulling teeth.
