Pat Toomey is the rare conservative Republican who is running for re-election with the support of leading gun-control groups, but it may not be enough to save him in Democratic-leaning Pennsylvania in this unusual election year....His stance so angered one gun-rights group that it is backing his Democratic opponent, Katie McGinty, just to send a message to Toomey and any other Republican who might deviate from orthodoxy on guns.
