I was going over the national numbers for the Democratic nomination. What stands out is Biden has the support of 50% of black voters to Sanders 15% and Warren 9%. One has to remember blacks make up one third of the Democratic primary voters. If those numbers hold, it's hard to see someone other than Biden winning the nomination. FYI, among white Democratic primary voters it's Warren 28%, Biden 20%, Sanders 17%.
If Biden wins the nomination, he still has to hang onto those black voters and there is a long way to go. Biden could go with a VP choice that brings regional balance, a women for gender equity, a black or Hispanic or someone from a swing state that would be able to deliver that swing state into the Democrats column. Klobuchar meets two of those requirements. Hillary won Minnesota by just a point and a half. Your Harris being black and a woman also meets two, but California is a foregone conclusion. Warren and Sanders are from the Northeast, that's the last region the Democrats need strengthening. The Northeast is theirs with the possible exception of New Hampshire.
Buttigieg is interesting, but I doubt he could deliver Indiana. Being a numbers guy, I'd look south. Is there someone from Florida, North Carolina, Texas that might be able to swing those Trump states into the Democratic column? O'Rourke Texas might be interesting, but he couldn't beat Cruz who was very unpopular. Maybe a bit of thinking out of the box is in order. How about a little know state representative who came within a runoff of defeating the Republican candidate for Georgia governorship. Stacey Abrams, a woman, black, would bring regional balance and most important, very well could deliver Georgia to the Democrats. Crazy, I know I am. Abrams has a reputation of working with Republicans in our state legislature to get things done. Now that might work against her. Then again, Biden had a history as senator and as VP for working across the aisle. Perhaps a duo like that is exactly what this country needs due to the division, polarization and ultra high partisanship that reigns today.
Four years as VP would in my opinion make Abrams the favorite for 2024 presidency.
