Earlier quoted context omitted.
Just because Fox News crowed about it doesn’t mean it’s bad journalism. Arguably toeing the party line is what resulted in Democrats being in that situation (fielding a weaker candidate against Trump) in the first place.
Framing someone who supports democracy vs someone who tried to overturn a free and fair election as a 'weaker' candidate is kind of the problem though. In any sane world, you'd support a literal corpse over a guy who does not want there to be free and fair elections.
No, you’d be serious about picking the best candidate you’ve got to stand up against the formidable foe. If all you’ve got is a corpse you might as well not bother.
