40-40-20, That’s the electorate, roughly speaking.
40% Democrats, 40% Republicans and 20% Independents and Libertarians.
Now, that 20% can be broken down as 40-40-20 as well. 40% Dem leaning, 40% Rep leaning and 20% clueless.
40% of 20 is 8%, 20% of 20 is 4%, so now we have 48-48 and a clueless 4% that will actually decide who will lead us for the next four years!......
Unfortunately, the clueless category includes those who vote party without knowing anything about the candidate.
