As a practical matter being a "pro-gun" Democrat may be real at the state level. At the national level it is meaningless. By merely caucusing as Dem he is defacto supporting whatever sick anti-gun policies the majority chooses to make law. Pelosi et.al. set the agenda, he is cooperating with them having the control to do that.
So he is *effectively* a gun banning liberal lesbian, even though we all know he's an ex-Marine packing heat. That's the rough and tumble of party politics.
LOL!
But seriously... By that logic, Mike DeWine was a right-wing gunnut. In fact, anti-gun Republicans can be counted on by the antis to support any gun control scheme they can dream up. When bad gun laws get passed, it's almost always an anti-gun Republican who casts the deciding vote. We're better off with pro-gun Democrats. At least with them, there's a chance that they might buck their party's leadership. On the other side of that coin, there little chance at all that an anti-gun Pubbie will follow the party leadership.
