I'm a first timer and am leaving all the info posting to the vets. Not gonna lie, I'm lost on most of it anyway!
The easiest way to look at all of this is there are only 7 US states that matter tonight. Wisconsin, Michigan, Pennsylvania, North Carolina, Georgia, Arizona, and Nevada.
Harris is banking on winning the "blue wall" states, which are the first three listed above to win the Presidency. Its not her only path to win but it is the most plausible one.
Everything else outside the 7 states is mostly irrelevant noise.
