Liberals in Congress Bad at Self-Promotion?

Interesting comment by Rachel Maddow on a segment looking into why the Congressional Progressive Caucus' proposed budget isn't being given more attention.

Rachel Maddow: "I will say that we get lobbied all the time on stuff to cover and you would think a show like mine would get lobbied all the time to cover all the liberal things. The sum total of lobbying that we've had on uncovering the progressive budget has been liberal wonks tweeting about it. That's sort of been it."
