OK, we can use this argument all over again to ignore all other factors that led to Trump's victory, and feel better about ourselves. The fact remains she blew a winnable race, just like Gore had in 2000.
This is literally the worst thing Democrats could do: cling to one reassuring talking point and be just as blind as before the election (except before it was overconfidence).
Good point Kal.
And of course the converse of this talking point is that the Democrats only managed to beat Donald Freaking Trump by <0.5%!
