Doing the math

In today's Los Angeles Times, columnist Ronald Brownstein writes on how demographics are changing the electoral math.
Brownstein writes, "[N]ew long-term population projections from the Census Bureau show that anyone who believes Democrats can consistently win the White House without puncturing the Republican dominance across the South is just whistling Dixie. The census projections present Democrats with an ominous equation: the South is growing in electoral clout even as the Republican hold on the region solidifies."
Brownstein cites research by Brookings Institution demographer William H. Frey:

In 2000 and 2004, Bush won all 11 states of the old Confederacy, plus Oklahoma and Kentucky. In those two elections it netted him 168 electoral college votes. That meant Democrats had to win about 73% of the remaining votes to secure a majority — a hurdle they found a little too high each time.
Frey projects that those 13 Southern states would cast 173 electoral college votes after 2010, and account for 186 after the 2030 census. If Republicans can still sweep the South at that point, Democrats would need to win a daunting 77% of the remaining votes to construct a majority.
