What is the threshold of EVs or percentage of the PV to be considered a landslide?
The following:
• Win U.S. Popular Vote by no less than +10 percentage points
• Carry no less than 40 (which are 80 percent) of the nation’s states
• Prevail with an electoral-vote score which is no less than 400
You are formulating parameters no candidate can realistically meet anymore. I could almost see Democrats (in a good year a few decades from now) getting criterion 1 and 3, but #2 is downright impossible for any candidate now, since there are definitely more than 10 states that are rock-ribbed Republican (look at ND; SD; OK; WY; ID; UT; NE; WV; KY; AL and TN for starters) and 10 similarly Democratic states that will never go red (MA; CA; HI; MD; NY; VT; OR; WA; NJ; IL; CT; RI, are just a few).
What could be realistically attainable is these restrictions:
-Popular victory by over 6%
-Carry at least 30 states (for Democrats) or at least 35 states (for Republicans)
-Win at least 340 electoral votes
