Could Romney's Continued Support For Rifle Bans Be His Achilles Heel?

After weeks of word-play about the 2A, GOP presidential hopeful Mitt Romney may have dug himself a deeper hole on Tim Russert's Meet The Press program last Sunday. True, his tortured explanation that he received an NRA endorsement (which he never received), came to light quickly in mainstream media and the blogosphere.

But his reiteration of support for a ban on semi-automatic competition rifles . . . well, it just isn't playing well.

BTW, can anyone define for me just exactly what is "a weapon of unusual lethality?"
