Honest question - what do you suggest they do?
I’ve been saying all year, as has Nikki Haley, that whichever party got Biden or Trump off the ticket would crush it in this election if the other one remained on the ticket. Trump gaining a big lead over Biden after Biden was exposed as a vegetable led to the Democrats replacing Biden on the ticket and now this is playing out about as I anticipated it would. Harris has given the Dems life despite all her flaws, because at least she can string two sentences together
I’m just not sure what you expected/expect the Republicans to do differently - change their candidate at the last minute to match the Dems? Not gonna happen, because there is enthusiasm for Trump that never existed for Biden.
