With respect, as it's not my party, Republican Party is stupid and corrupt. They take their members for granted, and feel very comfortable in ignoring them or even regularly screwing over their membership. There may be a MILD, VERY MILD, pro-2A gain under SHARE Act. Because they know they can give crumbs to their supporters and correctly assume their supporters will metaphorically be overfilled with joy for those crumbs. Because what are they gonna do? Vote for the other guy?
They're busy looking to get paid. Campaign contributions are certainly more important to them than their supporters. They can pocket the cash, screw over their own voters and be pretty confident they'll be voted back into power once the Dems overreach. This has been the pattern of my life. Dems pass way too many laws or try to reach much further than their grasp. Republicans are outraged, and vote. GOP gets a pretty healthy majority. Wastes it on a couple of token bills, focuses way too much on meaningless social crap, gets paid to pass legislation helpful to certain industries, gets thrown out for accomplishing basically nothing. Government grows, debt grows, regulation becomes more choking, wages stagnate, inflation continues to climb. Neither party want to do more than symbolic gestures.
If they MEANT to do something for their supporters, they would have had a concrete plan ready to go for Trump regarding Obamacare. Far as I'm aware, the bones of such a plan don't even exist so far. Let alone the miles of groundwork that still needs to laid.
But hey, not my party, so maybe I'm wrong about my impression.
