Well, Harris probably owns a gun. No surprise there. Lots and lots of Democrats/liberals/leftists I know own gun(s) and know how to use them. The notion that the RWNJ are the only people that own guns is a rather silly notion.
As for whether donnie will do anything for the common man - or if he "wants" to - is very debatable. He supposedly wanted to do something for the "forgotten man" during his failed 2016 term, but how did that go? I seem to recall the only thing dimbulb donnie did was to have a huuuuuge giveaway for the already comfortable, and all while his party voted multiple times to try to deny millions of Americans of healthcare.
