351: Sen. Hillary Clinton(D-NY)/Sen. Evan Bayh(D-IN)
187: Sen. John McCain(R-AZ)/Former Rep. J. C. Watts(R-OK)
Clinton wins the black vote 82-17. Large numbers of black voters in Virginia and North Carolina flip especially large as J. C. Watts campaigns hard there in October and November.
In 2004, when incumbent Republican president George W. Bush defeated Democratic challenger John Kerry in the U.S. Popular Vote by 2.46 percentage points, national Democratic support from blacks were 88 percent. (The winning Republican received 11 percent.) Between 2000, 2004, 2008, and 2012, Republicans reached 10 percent from blacks nationally only in 2004 (when they won the U.S. Popular Vote). That party's percentage from blacks, nationwide, were: 9 percent (in 2000), 11 percent (in 2004), 4 percent (in 2008), and 6 percent (in 2012).
You have, in your scenario, Hillary Clinton having won a Democratic pickup in the Electoral College with "351" electoral votes (up from the 252 mathematical ones from 2004's losing candidate John Kerry)…and, yet, you also have blacks having shifted Republican nationally as Hillary Clinton carries them by 65 percentage points (down from the 77 percentage points for John Kerry).
You need to rethink your scenario answers, Kingpoleon.
