They weren't in 2004. A Senator did sign a House member's objection to Ohio's Electors and the members debated and voted in their respective chambers.
This isn’t 2004. But we’ll see.
I think you may be surprised at the extent to which the DemoKKKrats and willing RINOs will go to get rid of Trump asap.
But regardless, the debate is limited to 2 hours per objection. You’ll probably have a 5 minute debate in the House (rejection) and possibly 2 hours in the Senate (rejection). Ultimately, the Hawley/Brooks challenge will get (I think, hope I’m wrong) no more than 10 senators.
