If going by the most recent polling data, New Mexico, Oregon, Utah, Indiana, Illinois, Mississippi, Kansas, Colorado, Alaska, Montana, NE-2, South Carolina, Missouri, and Texas are all more competitive this year than Maine. As are every other state you listed on the quiz.
Do you mean ME-2? Maine, like Nebraska, has some districts that vote apart from the rest of the state. That district does sometimes go Republican. But the rest of the state is pretty solidly Democratic.
Not a chance in hell. There is a tiny tiny tiny chance that either candidate gets all of these. Biden is not winning Ohio or Iowa by a long shot and Trump likely won't get close to winning Virginia.
