Which will never happen unless at least 1 of the 2 major parties is co-opted and taken over by people who specifically want to eliminate Citizen's United, put a strong, enforceable cap on private political donations, and block corporations from donating to campaigns.
A 3rd party is never going to be successful enough to accomplish any, let alone all of that. Republicans will never get money out of politics because it benefits them too much. It hurts the Democratic Party overall, but it directly benefits the Vichy wing of collaborationists leading the party, so they won't back campaign finance reform unless the Democratic Party is wholly overtaken.
Because people don't vote on policy, they vote on personality and vibes. It's how it's always been. This list of policies is (mostly) just a copypasta of the Democratic platform. But people have never voted that way. The Democrats put forth the crypt keeper, then replaced him with one of the most boring public speakers to come out of the Democratic Party in a generation. And they were running against someone who is a horrific fascist, yes, but also has stage presences and charisma and knows how to play to an audience. As much as he's one of the worst people on the planet, Trump knows how to make himself entertaining to watch.
That's what drives votes for politically disengaged people who don't pay attention to politics until the middle of October every 4 years. They listen to who is more entertaining and pretend like that candidate is telling them what they want to hear, regardless of whether or not he is.
