Trump is leading in PA by over half a million (600,000) votes.
The Michigan "flip" is by a measly 12,000 votes (2,511,000 to 2,499,000). And still 10% of the vote to be counted. Not saying it can't stay blue, only that the gap is too small to gloat over just yet.
Trump leads GA by over 100,000 votes, 92% reported. Could go either way.
Wisconsin is too close to call, they're separated by a mere 20,000 votes, with 3% still left to count.
NC is similar to GA, Trump is leading by a very small margin, 95% counted.
Obviously, these numbers are what is being reported at this time, and will change. Just wait and see. If last night showed us anything, it's that pollsters suck at predictions.
