The democrats have been losing elections for years because of their stance on gun control so why would the repubs want to join them? If any republican ever locks arms with the dimmy's  on gun control he's going to be political toast,besides it gives those hand wringing pants wetters on the left a bone to gnaw on so they dont use that time to champion some other issue or cause that may even be worse.Trump cant afford to loose the protection of his base by even listening to the democrats on gun control or he'd be abandoned left all alone and the demo's would finish ripping him to shreds.
