General Discussion
In reply to the discussion: Charles Grassley gets his ASS KICKED at a town hall over his gun inaction [View all]As the former state director for a United State Senator I assure you members of Congress hate it when a crowd of constituents gets in their face and shows disapproval. Most of the members actually are smart people (ok a couple of exceptions, especially in the past decade) but they all share the trait of wanting approval.
On certain issues they know a segment of their constituents aren't going to agree with them and they don't lose too much sleep, i.e. if you are firmly pro-choice or anti-choice for that matter, you know at least 1/3 of the population in your state/district will oppose you and it doesn't really matter. But the gun debate, in which the vast majority in every state and most districts definitely want something done, is a prime example of "the folks back home" actually having a lot of power to move the needle if they are consistently insistent that the member DO SOMETHING!
My guess is that the R's have seen the polling and know that it could actually snatch defeat out of the jaws of victory in the midterms. So look for some reform and major declarations of victory coming in the next month.
