States are given representation proportional to their populations, and also equal representation (in the Senate). The EC and House seats aren't just based on voter turnout, voter population, or even the actual number of citizens in the state (which is rather problematic). So this whole push for direct democracy in the presidential election is stupid. Yes, swing states are a thing, but only because the other states vote consistently in a particular way.
Another problem with using the popular vote to decide the presidential election is that it inventivizes fraud. If someone managed to corrupt a few populous states, they could generate extremely high numbers of fake votes to drown out every other state.
What do you mean here by "incentivizes fraud"? Lying on the campaign trail is not fraud. In any case, the same argument about fraud still applies, you just need to target swing states.
I think it's obvious what fraud I'm talking about: fraudulent votes. It stands to reason that a large state can generate more fraudulent votes than a small state can generate legitimately. Fraud is always an issue but it is more of an issue with popular vote because who can question extremely high voter turnout?
