And by not voting, you don’t get to have your highest priorities addressed. If my highest priority were banning abortion, I would have definitely voted for Trump because he would appoint anti-abortion justices. If my highest priority was criminal justice reform - I would vote for Clinton. Yes, I know she and her husband were part of the problem in the 90s.
Your argument makes no sense and is predicated upon an unknown future. Logically, you support who you vote for.
Every politician breaks campaign promises and Trump is no exception. Now if you donate or otherwise contribute a lot of money to a candidate then they will support you. That much is clear and it does not take a lot of money. The only reason we don't have gun control is because the gun lobby has enough votes in Congress.
Define "gun control" with specifics? I'm not against gun control for the reason most people are. For me, it's more practical. The government has never been able to successful ban anything that people wanted - e.g. "The War on Drugs". When they do have a "War" on anything, it's usually not evenly applied.
Ronald Reagan was all for gun control in the 60s as was the NRA when the Black Panther Party started legally walking around with guns in California (the Muliford Act). You want to see gun control? Start encouraging as many minorities as possible to apply for open carry permits.
