The anti gunners have lost two of their biggest arguments.
1. The second amendment only confers a right to keep and bear arms for those citizens who are members of the national guard.
They lost this one in Heller and the exclamation point to their loss is about to be added in McDonald.
2. More guns will necessarily result in more crime.
Gun purchases continue to increase while violent crime continues to decrease. They will find it tough to convince all but the most fervent gun controllers that more guns will necessarily lead to more crime.
One other area they are also losing on is the need for a national gun registry. Our neighbors to the north provide ample evidence that this would be extremely costly and ineffective in reducing crime rates.
Thus, they are either at or approaching the point of "3 strikes and you're out".
"If you love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you and may posterity forget that ye were our countrymen." Samuel Adams.
