Some want to limit your vote to Democrats or Republicans. Democrats tried to keep the Green Party off the ballot (in Texas?) and Republicans tried to keep Libertarians off the ballot. Both unsuccessfully.
Great! Those are TWO races. By my count, you need to run in 216 MORE RACES in the House and 51 in the Senate to be considered a legitimate 3P.
Why do you think the 3P ballot is so top heavy? Where are all the 3P's downballot to deliver this unicorn??? They aren't there and they'll NEVER be there simply because they aren't trying to build a political party or even build a political movement...all they're doing is grifting you. They find it so easy because you already have your head up your ass.
