You don't understand the basics of a First Past The Post system.

I do, and asserting that I must not because I disagree with your analysis is juvenile and insulting.

Let's say, for example's sake, that 52% of the people voting tend left, while 48% tend right, and let's also remove all the state, gerrymandering and grand elector bullshit for a moment (I know, so much bullshit)

Tons of bs, sure, but let's go with that.

If everyone were to only vote for either the Democratic Party or the Republican Party, come November, the Democratic Party would win with 52% of the votes and secure the presidency. Now let's assume that there's a third party, let's call it "The True Left Party" and let's say they can have a very successful campaign and secure 5% of the votes, which would come from the left leaning side of the voting pool, aka from those who would have otherwise voted for the Democratic Party. Now come November the results would look like this: Republicans still at 48%, Democrats now at 47% and True Left at 5%, so now the Republican Party wins and Trump becomes president.

No, if 52% voted for a Left party, PSL or the Greens would win. The 5% for the "true left party" isn't coming from the liberals that vote for and support the DNC. You're assuming leftists to automatically vote with the DNC, which is a false narrative. The DNC doesn't represent the Left in any capacity, nor do they pander to Leftist voters.

This is how voting for a third party only helps your enemy. If I were the Republicans, I'd be turbo donating to any left party right now. Divide et Impera as the Romans said.

The DNC are the enemy of Leftists as well, neither the GOP nor the DNC represent Leftists, which is why your previous paragraph doesn't add up.
