Real Clear Politics is a lib site. They list articles from Huffington Post, Daily Kos, etc.. and their poll averages include polls from PPP, Project New America and Democracy Corps. They sold out a long time ago.
Noticed that too, BC. I only like to go there to look at the polling internals, do my own calculations and laugh at the parallel “narrative” of what the LSM wants, to sell pol ads, and the more accurate statistics of the political climate.
