Mitt Romney did that to himself instead of simply saying I stand by my statement he let Crowley correct him in real time. Mitt was just a bad candidate when he literally made his convention about him being more likeable and then he adds a Chris Christie as keynote speaker whom literally didn’t mention Mitt Romney’s name till 20 minutes into his speech.
Trump is Trump if he thinks Joe is lying he’ll say so and if he thinks the moderators are protecting him he’ll make sure to point that out too.
If Biden fails, he will not be nominated at the convention and instead a search will take place for replacements, because they are not going to select Harris, for she's an even bigger disaster than Biden. They only picked her as Biden's running mate to ensure that Biden wouldn't he impeached & possibly be convicted if the midterms happened to change Congressional control. The could afford to lose the House, because they had enough RINOs in place to negate any real threat. But they has to hold on to the Senate.
So, let's see how my predictions go.
One last thing:
They will try to gaslight people that the economy is much better than the people realize, but that won't fly with most whose lived life sees the reality that life has less quality under Biden than it did under Trump.
