An assault weapons ban has been Obama's second term plan all along. During the debates he said he would work toward an assault weapons ban. He did nothing about it in his first term intentionally in order to be able to win reelection. He has kept much of his agenda secret to get another term I'm afraid. I hope I'm wrong for all our sake.
With this point I agree 100%. Bad news is coming. Besides Comrade Obama, who is on record saying that no citizen should be
allowed to own a handgun, we have Silly Hillary, who will be back helping the UN with its gun ban agenda. So far, the worst done by BO and Co have been done behind the scenes (barring reimport of M1 Garands, Fast and Furious, and others), and they are likely to continue that. With luck, BO will do something even more impeachment-worthy and be taken out of office.
I only suggest holding off on your congressman until you have something specific to write about. Fortunately, my congressman (7th District, Texas, Republican John Culberson, just reelected) is conservative and pro-second amendment. On issues that matter (illegal immigration, taxes, deficit spending, etc.), I usually hear his position in his emailings before I even have a chance to contact him. Our continuing Senator John Cornyn is a windsock, so is currently in line with us conservatives. The newly elected Senator Ted Cruz looks good if he is half what he campaigned on.
I'm sure that an hour from now (9am central time), there will be the first round of panic buyers at my friendly local gun shop. I read a while back that Glock doubled production for the U.S. months ago in anticipation of this day. I have to confess: I'm thinking harder about that G32 (.357Sig) this morning myself, as well as another half dozen 30-rd AR mags and another 1,000 rds of 5.56. The safe is already full of .45.
