True, but the word "blowout" in this case is just a crazy side-effect of our weird electoral college system.
Everyone knows that in all the swing states (except Arizona), the final vote margin was just a few percent, and that was well within the MOE for all the "50-50" polling in each of those states.
No one seriously believes that any President has had a blowout election since maybe Obama in 2008 or Bush in 2004, but the media sure loves the word "blowout".
