The motion, put forward by Senate Majority Leader Chuck Schumer, would have reauthorized the Assault Weapons Ban, which first passed in 1994 and expired 10 years later. The US has recorded the highest number of mass shootings for the second year in a row.
Imagine just for a second, that they drop the issue and gain control of all 3 branches and then actually do something about it rather than constantly struggling to win because of single policy voters.
The only thing tougher to imagine than dems winning supermajorities and all three branches is the dems doing something with it. Hard to imagine the people who fund splinter dems like Manchin wont just do the same thing to a dozen dems instead of two.
