Undecideds are non-voters.
For 100yrs between 40% and 52% of eligible voters have NOT voted in EVERY presidential election (it's even higher non-voting in midterms). 1960, 1964 and 1968 had the highest voter turnout ever: 63%. 1924 and 1988, the lowest: 48%

Traditionally, second terms of incumbents have lower turnout than elections where there is no incumbent and an open field. 2004 was 6pts lower turnout than 2000, 2012 was 5pts lower turnout than 2008. 2016 was up from 2012 but had the highest 3rd party voting since 2000.

Races with 3rd party candidates that made it to the debate stage--George Wallace in 1968 and Ross Perot in 1992 and 1996 have made it impossible for the winner to get 50% of the vote. In 1968, Wallace even carried 6 Deep South states.

The last highest Electoral College win was Bill Clinton in 1996 where even though he was up against Dole and Perot, he won 370 electoral votes.

In 2012, Obama only won two states + DC more than Romney. That is how tight and scary the Electoral College is. Because Hillary only lost three states--and lost the Electoral College despite winning the popular vote by close to the same numbers as Obama's pop vote over Romney.

So as Hillary said at the DNC2020, every vote counts and remember you can win the actual votes by 3M and still not be president. Biden needs a 1968 turnout with a 1988 win.

So in 1992, Bill Clinton won by 8%--even against incumbent Bush 1 and Perot. He broke the GOP stranglehold on the presidency which had held for all but 4yrs from 1968 till then. Obama 2008 won by almost 7%. But only by 3% in 2012--and just 2 states + DC.

In 2016, Hillary got the same number of votes as Obama 2012 and won by nearly the same point spread--but lost the Electoral College by the reverse of Obama's 2012 win. The last incumbent to lose was Bush1, who was ostensibly Reagan's 3rd term. There is NO room for complacency.
