I think that the general rule is: liberals/Democrats/MSM types such as Chris Matthews can tell all the jokes they want, about any subject, but, Republicans/Conservatives attempts at humor are ALWAYS in bad taste, evil, hurtful, you name it.
Dumbass thinks this chit is all a big joke and he's the phakin' punchline.
