The Weather Underground took over the Democratic Party. Obama was their boy.
The CPUSA merged with the Dems.
There are at least 3 congressmen who have received special awards from CPUSA.
AZ Congressman Raúl Grijalva
IL Congressman Bobby Rush
Sen. Richard Blumenthal
There may be more but those are ones I know about.
I even saw a video long ago when Grijalva received his. Video shot as he was leaving the building.
