true.
But here’s the problem: There is perhaps a third of Democrats for whom NO amount of evidence will ever change their minds. So yes, IF it were proved they would abandon Biden, BUT IT CAN NEVER BE PROVED!
In other words, there is a proportion of “dead-ender” Democrats who simply can’t be convinced by data or evidence and will “vote blue no matter who.”
So yes, it’s great that nearly 2/3 of Democrats say they would vote against Biden if he were proved to be “dirty.” But realize that for a significant proportion of those it is a false dawn, because they could never be convinced of it!
They hold to their tribe with religious intensity! Because, in fact, it IS a religion for many of them.
