re: Biden is going to lose the race on border policy alone.

There is always a "surprise" every election. Part of the problem is organization and how it is worked. Democrats are very good at identifying up and coming constituencies that would be sympathetic to their message. Plus they understand demographics so much better than Republicans and conservatives. See GA and AZ. You can debate about whether there was fraud, etc. But you have to ask if Trump had won these states by razor thin margins, why was this so? For decades both of these states were reliable Republican strongholds....Clinton Admin notwithstanding. Even in 2016 both provided comfortable margins for Republicans......or did they?
