What do you think "districts" means? Each district gets represention for the whole body, whatever body that may be. If you need that explained to you, okay, but don't then lecture others on minutae of semantics when you arent familiar with what the word "district" entails.

And the U.S. President is not elected like this, no. There is no districting involved in US Presidential elections, at least not currently and not directly. It is far stupider than that, unfortunately. Each state has so many districts on the federal level based on population of the whole state (minimum 1), and each district gets a federal representative in the US House of Representatives wing of congress. Each state also gets 2 and only 2 Senate seats regardless of population in that wing of congress. The Presidency is actually determined by the votes of Electors in the Electoral College. Each state gets as many Electors as they have seats in both the Senate and House, and it has nothing to do with how the districts in that state are subdivided or what party their Representatives are from.

Now, each state gets to determine for itself how they run their elections, how they assign their Electors, and even whether their electors are required to vote the same way as their state, so things can be pretty complicated. In many states, it is winner take all for that state's Electors, with the winner being the one with the plurality of votes in a FPTP election, which is dumb as fuck. Some others assign their Electors proportionally. There is even a slowly growing coalition of states that, once they reach a plurality of Electors in the coalition, have agreed to no longer assign their Electors on a state by state basis, but on the national popular vote instead. Again, within each of these states, rules differ on the relative power of the Electors themselves to vote according to their own desires even if that goes against the state's popular vote. They could, also, if they wished, leave each House-tied Elector up to each individual district, or just decided the Electors without considering or even having a democratic vote at all, neither or which currently happens, though. It's a giant fucking mess, it leads many many people in hard red or blue states to just to just not bother as their vote will be overwhelmed anyway, which is why the Electoral College should just be eliminated and replaced with a national popular vote. But that is a whole other story.

Except that the lack of a third candidate is partially because of the FPTP system.

Right, that's what I said in my previous comment. Ranked Choice is an improvement, yes. Though, I think it still is too easy to push the winning vote to the more polar candidates. If the centrist doesn't rile up passionate supporters (because what centrist does), they are more likely to be dropped in the first round even though they were ranked 1 or 2 for nearly everyone. I prefer Approval voting as my ideal alternative. It does tend to push more toward center, but if the idea is true democratic representation, then that would be the natural result, right? But anything is better than FPTP.

I don't understand it well, but I like your 2 round system. What are some typical flaws with it that might not be obvious? I'm also curious what is the best thing about it, in your opinion
