First, I'm not sure she will get the nomination.
Secondly, even if she does, I'm not convinced she will win. The media may be trying to anoint her, but Obama or more accurately, a "black" candidate is throwing their liberal positive discrimination for a loop.
Even if elected, she needs a huge majority in both Senate and Congress to get anything like another AWB through, and she may not get that at all, even with a Democrat majority as many of the new dems were pro gun and anti AWB.
Hitlery is at least somewhat a political pragmatist and my guess is her "hillarycare" and other socialist agenda items will be more important than trying for a gun ban that she knows caused her husband and party so much grief last time around. I'm not saying she won't try, but I think she has other fish to fry first.
My worry with any Democrat is more how badly they'll screw things up with a massive income redistribution package consisting of moving money out of the hands of the upper middle classes and to "the poor". The uber wealthy will be unscathed as usual.
