Gun violence is a problem that the Democratic Party is responsible for. The vast majority of gun violence is conducted by Democrats against other Democrats in local jurisdictions that are controlled by the Democratic Party (and because those local jurisdictions span states of both parties, it's not the state party that's at fault). It's really sick for Nicole Wallace to constantly blame someone else like Republicans when it's Democrats who are most at fault for gun violence, mostly affected, and mostly already have the political power to enact any change they want to to solve the gun violence problem. But the Democratic Party constantly fails to fix the gun violence problem that it owns. It is a failure.
