in the 2008 election, Obama got ~69.5 million votes, McCain got ~59.5 million, out of ~129 million votes total (excluding votes for other parties' nominees for simplicity). of McCain's ~59.9M, some small number `x` is racists, who voted against Obama, because they didn't want a black President. after the end of Obama's first term (again, for simplicity), some number `y` is people who voted for McCain who were vocally displeased with Obama's presidency (presumably this number includes most if not all of `x`), and some number `z` is people who voted for Obama who were vocally displeased with Obama's presidency. everyone (racists, Obama-likers, Obama-dislikers) who did not exercise their Constitutional right to vote are irrelevant. `x` is a much smaller number than `y` plus `z`, so as to be insignificant.
