I disagree. While that's probably the case nine times out of ten, just because somebody is in a higher power seat doesn't mean they got there because they're greedy.
There needs to be change and protections at higher levels of government too.
Unless it is a local election, you have no chance of winning unless you're in one of the two main parties. So candidates almost always choose to join one of the parties.
This is pretty much what's happened with my latest character.
I'm playing a reborn/dragonborn, who had previously tried to fight Strahd but lost. And a part of that loss means that my character lost a good chunk of his memories of fighting Strahd before.
But Strahd still remembers my character. So it has lead to some interesting interactions.
This person decided to be a member of a party supporting a genocide just like someone decides to become a trump supporter
Here's the thing though, Americans don't have the luxury of going to another party, because only two of them are viable. So if you want to make political change your choices are incredibly restricted.
And I am sure many would leave the DNC if they had the means and ability to be accepted elsewhere. Unfortunately our electoral systems are set up so that if you're not in one of the two parties, your chances of winning are nil in many cases.
You're basically saying that there is zero overlap in the venn diagram of third party voters and blue voters, yet you make efforts to convince blue voters to go third party. You know damn well that there is overlap between third party voters and blue voters, otherwise you'd never talk to them.
Even if you personally would never vote blue, third party voters are not a monolith, there are third party voters that are closer to the DNC than you are.
It's a double edged sword.
