Why aren’t there moderate Democrats who don’t take money from corporate donors?

[Hardkill]

We all know that’s most Democratic politicians in this country take money from corporate including every conservative and moderate Democrat out there. Some of them have “pledged” that they haven’t taken any money from corporate lobbyists, but we all know that that is total BS. 

If progressives have had the integrity and will to genuinely deny all corporate donations, then why haven’t all of the moderate Dems done the same?
