Primaries are for voting with your heart, the general is for voting strategically

used to be... now it's fascism vs. center-right

Is it really center-right? I think it is more far right and facist extreme right. Atleast when observed from scandinavia

There is but you have to think of each party as having sub-parties within them. There aren't external coalitions between parties but internal coalitions within the parties.

So a guy like Bernie Sanders is left, though not technically a Democrat, he caucuses with the Democrats effectively creating a coalition. There are many members within the Democratic Party that are also left wing, and others that are center, and others that could be considered right wing.

The Republicans are similar, but have an internal coalition with the far right MAGA faction. Which causes them a lot of problems.

The primary system is effectively a run off system which is used to determine a final two candidates to vote for in the final election. This system is old and has some bizarre traditions and has vulnerabilities to there being a third party spoiling everything.

Obviously it's a crusty system that developed without planning, but the the Presidential election it's not that dissimilar to France's run-off system, just takes more time. And the legislatures having coalitions between people with different politics happens everywhere, it's just happening within the parties and requires people to vote in primaries to get more representatives that have similar views to their own to make up a greater percentage of the coalition (which also happens everywhere).

In fact having coalitions within a party gives people more information when voting. If I'm voting for one of a dozen parties I don't have a say over how a coalition is formed after an election. Someone declaring which coalition they intend to be a part of before the electorate votes gives the electorate both a say as to which individual they want (via primaries) and which coalition they want (in the general election).

That's why OP wrote "leftist" instead of leftist.

there's "administration aiding a genocide, but also doing so because they're being lied to by israel, who also has a massive propaganda campaign to manipulate americans into supporting them..."

versus

Project 2025 and their plans of a fascist dictatorship right here, complete with a genocide of trans people and hispanics... and muslims... AND a continuation of supporting israel...
oh and aiding russians commiting genocide in ukraine.

voting trump in won't save palestine, and it'll make it soo so much worse

Do you really believe not voting for Biden deceases the likelihood of genocide in Gaza? Because the alternative seems so much worse in every way, both for Gaza and so many other massively important issues

And I'm sure letting trump have an easier time getting elected will make things so much better.

I would recommend talking to your local representatives about the current situation and how important it is to you and expressing how you may support other people running against them if they don't support a ceasefire.

Local elections are really important.
