The USA Today has a table that shows how much money all the freshman representatives have raised so far this year. It breaks it down between individual donations and PAC contributions. It’s amazing how strong the correlation is between good voting and getting the majority of your donations from individuals.
Almost without exception, every representative that has raised more in PAC money than in individual donations, is a Blue Dog or New Dem or a Republican.
The most progressive voices have the largest individual donor ratio advantage. In the past, progressives wound up with no money if they didn’t get PAC money. As you can see from the chart, that is no longer the case.
