[float=right][/float]Whitmer replacing Harris would boost Biden a few points once voters see a competent, well-spoken potential future President.
But the social justice mob won't allow it. They are determined to run with Harris and use her loss to prove America is a racist country.
Whitmer is staying Gov until 26 and Biden is doing all right in polls in MI
My issue with Harris is in terms of support and ideology, she really runs more in the Elizabeth Warren lane than the Obama lane. Her base is more elite educated college whites and a focus on gender identity issues as opposed to cost of living, economics. While certainly not in the Sanders lane that these college protestors are in, her ideology just does not appeal to very many people, including very few working class non-whites.
Whitmer OTOH has amassed a very deep coalition in both her victories that keeps 100% of Biden 2020 supporters and further expands the coalition.
