If you instead awarded EC votes proportionally, you'd largely wind up aligning with popular vote entirely. It'd also make more states more competitive, since it is much easier to move the margin on one electoral vote rather than say 55.
No, it doesn't. The US has indirect elections for the head of state, but the body which directly elects the head of state literally does nothing else.
The results are passed on via electors, but most electors are bound by law to vote alongside the popular vote of the state. Even when not bound, they have almost exclusively done so, making this particular fact more of a technicality.
An indirect analogy based on the Canadian system, for instance, would be whichever party in the House has the most seats gets to put their leader in the President role. I would consider that to be "indirectly."
Canadians are never asked "Who should be Prime Minister: Justin Trudeau, Andrew Scheer, Jagmeet Singh, Elizabeth May or Yves-François Blanchet?" Parliamentary procedure dictates that.
They don't, though, they vote for (mostly, there's a few exceptions) statewide slates of electors.
> Americans are picking on the ballot between "Trump" or "Biden," not "Republican Elector Steve Ruralson" vs "Democrat Elector Bill City-Slicker."
But that's because the ballot is a lie.
The distinction you're highlighting is a very important piece when it comes to discussing election reform, but I think it's better to classify it as an inaccuracy in the manner in which the electorate votes for the head of state - rather than as the electorate not voting for a head of state.
The Canadian system has you pick your local representative for your riding (MP) and the party with the most MPs, traditionally™, gets to make their leader the Prime Minister. The popular vote is irrelevant because the popular vote is not how Canadian elections are 'scored.' At all, really. Each race is a race for your specific representative. That it's correlated with the PM-ship is ancillary, since even a plurality of seats doesn't guarantee your party ends up picking the PM. A coalition of two smaller parties can band together and unseat a plurality party for the PM role. A Conservative-NDP coalition (haha) could have installed Scheer as PM after the last selection. A Conservative-Bloc coalition could have done so too. And a Liberal-NDP coalition could have installed Trudeau as a majority leader in the last election.
In the US, they have FPTP voting specifically for their head of state, which is where the rub lies. You have a poll for who should be in charge, but you weight the votes differently depending on which state those voters happen to reside in, and throw some of them away (via FPTP). This is intentional, to ensure that rural states have outsize representation. A good idea? Maybe not, but it's no mistake.
[edit] Re: the BQ, they've started campaigning not on separatism but on social issues, it's cool to see honestly.
