Is it just me, or is there something really odd about Trump going to Colorado, California, and New York to campaign? It doesn't add up that he'd spend the time and resources holding rallies there when he knows he's not winning those states.
The two reasonings I can think of, which are not nefarious:
1) He thinks he can win the popular vote and wants to run up his scores in blue states to ensure it happens. He will lose all three of those states but (in his mind) a significant increase in voters there will pad his total vote numbers.
2) He's doing what he always does: grift. Currently he has a NY fundraiser scheduled for October 27th, including 250k plates/tables lmao. Could be the last influx of cash he sees before the election, and the last cash he sees for awhile if he loses in November.
