I’m absolutely serious. In case you didn’t notice, Hillary was by far the weakest candidate that the Democrats ran in decades. Even the grassroots of her own party didn’t like her, especially the Bernie-bots. Low turnout among the base would have done her in, while her overwhelming negatives would have motivated conservatives and Republicans to vote against her (almost) no matter who was on the GOP ticket.
If you actually believe that Bush would have beaten Hillary then you are a political idiot.
