Seems like PA's latest polling has ever so slightly shifted towards Trump (+1) whereas NV (Even) and NC (Trump <1) are tightening further according to the NY Times. Certainly, this is a ridiculously close one even if the EV totals don't end up being that close. It does seem possible under certain circumstances that Trump could win the popular vote and lose the electoral college -- something seen as impossible just a couple of months ago.
Kamala really needs WI/MI/NV and then one of PA (276 EVs) or NC (273 EVs). Trump's best path seems to simply win PA and NC -- that would put him in the White House at 281 EVs. He could also do PA + NV and lose NC to get 271. He has no path if loses PA basically. Unfortunately, PA is going to take forever to count so I suspect oddsmakers would put the odds of us knowing the president at the end of Tuesday night as a <50% proposition unless polling is skewed one direction. We'll be able to see if WI/MI are aligned to polling which could give us insights into how PA might go.
For people who don't care about the outcome and are more political junkies about the numbers, this could be a fun affair. For most of America, however, it is not....
