Tips on contacting your Congressthing:
"You miserable so-and-so" --Okay
"I hope you are severely beaten by syphilitic mandrills flailing barbed whips" --A happy thought but Not Okay
"Your [vote/comments] on [issue] has cost you my vote" --Okay
"And my minions have redone all your topiary in rude shapes" --Not okay; likely actionable
"You should be ashamed to show your face in [district]" --Okay
"There's a pie aimed at it if you do" --Not okay during Reagan administration and still not okay. Actionable.
From what I read in the papers, you're simply nobody among D.C. Democrats unless you've received threats* (and Republicans are gettin' 'em, too). Don't give 'em ammunition. Especially don't give the media yet another excuse to paint the American public as an unruly mob in need of governing from above. Be polite, be firm and GET OUT THE VOTE! Remember, they can't throw you in jail for that -- yet.
* As we all know, no politician anywhere has ever received threatening calls or letters before now; Congresscritters were never jeered in public nor greeted by angry signs and angrier shouts. Oh my doodness gwacious no. I'll be over in the corner, hurling not rocks but my lunch back up.
