Wednesday’s House vote on legislation expanding background checks for gun sales is a top priority for a handful of Republicans from more moderate districts.

But while they’re largely in line with public opinion on the issue — and with the chamber’s new Democratic majority — they’re at odds with other Republicans in Congress.

And some former and current elected Republicans worry that more of the conference isn’t backing the legislation, given the drubbing the GOP just suffered in the suburbs last fall.

Five Republicans and 227 Democrats have signed on as co-sponsors to legislation that California Democratic Rep. Mike Thompson introduced last month. Despite the partisan imbalance, they’re calling it the Bipartisan Background Check Act of 2019.

More Republicans could ultimately vote for final passage Wednesday.
