Well, Sanity, I agree with a number of your observations. There are no major differences between the canidates we are left with after the nominating process has concluded. Frankly, there wasn't all that much difference before the nominating process begain. So we are stuck trying to correct the course of the country by making very minor changes.

                   I think it helps to look at it this way: if a ship is sailing across the Pacific from, say, San Francisco and heading on a general course to Asia, and somebody sneaks on board and changes the rudder just one degree, the ship will end up in a very different place than if that person hadn't snuck on board to begin with.
