No one is saying to vote dem and just sit on the couch waiting for a miracle.
Vote for democrats but organize, pressure legislators, local politicians, etc
Unionize so your voice becomes louder and you gain bargaining power.
Hold the the democratic party accountable for its BS. Try to steer it more left instead of right.
Educate those around you about the importance of a fairer voting system and the need to fight fascism and get them involved too.
Participate in all elections you can to make sure you give power to those who can actually help you.
There’s so much you can and should be doing beyond voting.
And the democratic party has in fact moved left, even if it doesn’t always seem like it. These things take years and decades, especially for a country like the US where all the stops are in place to make sure change never happens. So yes, reform is possible. It’s slow, painful, and sometimes it feels like you’re accomplishing nothing, but things are changing. They won’t be changing for the better if Republicans ever win though.
So telling people to vote 3rd party, at this point in time, when the US is constantly being bombarded with fascist propaganda, when the education sector is eroding by the day and people are completely politically disenfranchised because of it, is literally just splitting the vote without sending any message or moving the country forward and giving Republicans a win.
If you want 3rd parties to win, instead of praying millions of people magically switch sides, start by getting people actually interested in even caring about politics, because otherwise it’s never going to happen.
