Chairmanships are extremely important, also the majority leader. If Reid goes down and the Rats retain the majority Schumer will be the majority leader. I shouldn’t have have to spell out what that means for the 2nd amendment.
I'd be interested in hearing you spell out how they'd pass anti-gun legislation with a Republican majority in the House, enough Republicans in the Senate to prevent cloture, and a crapload of Democrats in office that wouldn't touch gun control with a 10 foot pole after the lesson they learned when they passed the Assault Weapons Ban.
As an alternative, you might consider what lesson the Republican politicians would learn from having the people vote in somebody like Castle with an F rating from the NRA.
And...it shouldn’t have to be spelled out for you that your repulsive RINO Castle would kiss Shumers ass and vote with him against the 2nd amendment.
