To add a counterpoint - it seems to me the main reason the democrats are antigun is that is where most of their funding comes from. When you take money from Bloomberg or Soros you agree to be antigun. This is not something that is controversial to say, Bloomberg and Soros are very proud of it. They directly inject vast sums of money into local elections to force in anti-gun candidates, and they have been very successful at it.

Despite your own personal viewpoints guns are very popular in the United States among both parties.
