Seems the best way. The key is the primaries. Conservatives have to show up for the primaries. Avg voter participation in primaries is 25%. It should be at least as high as the general.
Not voting and 3rd party only helps the LEFT consolidate power.
The 3rd party may not win but at least you are not voting for people that hate you and don’t have the same beliefs that you do. There are few that do in the Weasel (Whig) party and they would probably join the 3rd party.
