Here's a clip from Neil DeGrasse Tyson's response when asked what he'd do if he were president.
One objective reality is that our government doesn’t work, not because we have dysfunctional politicians, but because we have dysfunctional voters. As a scientist and educator, my goal, then, is not to become President and lead a dysfunctional electorate, but to enlighten the electorate so they might choose the right leaders in the first place.
