What was his formerly deplorable attitude? I thought Trump has been a longtime concealed carrier himself.
He once supported "assault weapon" bans. He seems to have dropped that foolishness (some time before his current run for President), and come out in full support of the Second Amendment. His early supporters assured me that his son(s) had some positive influence on him in that regard. I, for one, applaud that change. A wise man recognizes his errors and corrects them.
