I'll believe it when I see checks going to the RNC and not the DNC. That is not occurring. Clinton is running around the country collecting bags of cash from Jews. Older people donate most, they are also the most Democrat (95% over 65 in Philly voted for Gore, 78% of those 30 to 49 voted for Gore).
Another problem is this supposed great shift is fueled by identity politics. The GOP doesn't play that game much at all.
