These third party types always claim that they want to reform the system. That’s bullshit. If you want to reform this system then you need to start at the bottom. You need to recruit candidates and invest in winning at local and state level first. Those are the most winnable offices for an outsider/independent. Hell, win a few critical states and you can get enough states in the National Popular Vote Interstate Compact which, while not an ideal solution, would be a good first step in reforming the system.
Once you have some power and recognition at the state level, you need to aim for Congress. Start winning seats in the House and Senate and you can really start making change. That is where the real power of change resides. How many times have we seen a president with a divided House and/or Senate have their policy goals effectively neutered by legislative antagonism? Without support from the House and Senate, a 3rd party president would be powerless.
Stein cannot possibly enact positive change even if there were a literal miracle and she became president. The only thing, literally the only thing she can do by running for President is get Trump elected.
It’s actually worse than that.
A very large number of people are sitting in their trailers, drinking a PBR, and thinking that repealing Obamacare is a good thing because they got their insurance through the ACA.
