So, which states should you be tracking on Tuesday? We would argue that the "Swing Six" are (in no particular order): Arizona (11 electoral votes); Florida (29 electoral votes); Georgia (16 electoral votes); North Carolina (15 electoral votes); Pennsylvania (20 electoral votes); and Texas (38 electoral votes). Georgia, North Carolina, Texas and Arizona all have hotly-contested Senate races—which can have a dramatic impact on the presidential vote. Early in the evening, if the President is not doing well in Georgia and North Carolina, it could spell trouble for his re-election. On the other hand, if Arizona unexpectedly turns red later in the evening and Pennsylvania is close, it's a warning sign for Biden.
Now for the speculation. As things stand now, we would expect both Florida and Texas to go to Trump—although that is not a dead-lock certainty (what is these days?). North Carolina may flip to blue, but it seems that Georgia will stay in the Republican column. Again, no guarantees on either. So, the race seems to actually be coming down to two states: Pennsylvania and Arizona. Both campaigns have been spending time and resources in the Keystone State in the final days, while Arizona hasn't really gotten the attention it deserves. The most recent polls have Biden up in both states—but only by around three points in Pennsylvania and one in Arizona. Clearly, they are both up-for-grabs. All other things being equal, if either candidate can capture both on Tuesday, that person will likely win it all.
Because of varying deadlines for counting early ballots, we may not know the results in some of these six states for quite a while after Tuesday night. So, fasten your seat belts.
