From Representative Vicky Hartzler (r) early today, via Twitter:

Rep. Vicky Hartzler ‏@RepHartzler

A victory for gun rights! A judge has ruled Chicago’s ban on gun sales as unconstitutional! 6:50 AM – 7 Jan 14

And some push back, via the same medium:

Jim Kuhn ‏@Kuhnlake

@RepHartzler Oh good let’s celebrate! More kids get shot! You’re a real American patriot you stupid NRA mouthpiece. 9:38 AM – 7 Jan 14

Well, it is much more immediate and public than a sternly worded letter to the editor.
