Trump, for being more incompetent than DeSantis. Either one will become President, even if the Democrat wins in a landslide; there's nothing stopping a GOP House from certifying Trump as the winner no matter how much the Democrat wins by. Therefore, since I think DeSantis would be a more dangerous President than Trump, I'd rather it be Trump.
Remind me again how many Republican Senators voted to object?
You need a majority of both chambers to actually rescind the electoral votes of the state in question. A majority of both chambers would need to do that in enough states to eliminate the (presumed) Democratic electoral college edge. In 2020, this would mean you would've had to successfully object to 3 or 4 states in a row to get Donald Trump to "defeat" Joe Biden.
It's not going to happen.
It was never going to be successful in 2021. If Republicans hold both houses in 2025, which is likely, I expect a lot more to object.
