My theory about this, and I’ve expressed it before on other threads, is that the election could rest in the hands of a growing proportion of the electorate many refer to, crudely but accurately, as the free s*** vote.
One of the prime characteristics of this voting bloc is apathy regarding the charisma or policies of the candidate. Just so long as said candidate promises a continuing supply of free s***, they’ll get elected.
This phenomenon has been in operation since FDR and has become a growing factor in elections ever since. That’s why Romney got into trouble for his 47% remark in 2012. It was too true to make people comfortable.
Free s*** voters are not gonna be bothered to show outward signs of candidate enthusiasm. If they do, it’s just icing on the cake. If they don’t, is doesn’t mean squat.
That is not a theory; it is a fact.
There is yet another block of voters that are not being polled. These are the Americans who rarely, if ever, vote, and are fed up with the system. I know a 38 y/o male in this category who recently registered and will vote this year, for the first time in his life! He is voting for Trump.
