Ruffini's Warning

Republican strategist Patrick Ruffini believes that swings within the young voter demographic can account for Obama's victory -- and he's worried.

People have been focusing on whether the youth vote was up. It was -- slightly: going from 17 to 18 percent. But the real story about the youth vote is not how many "new" voters Obama got to show up. It's how he produced a gargantuan 25% swing among existing young voters, or those who were sure to vote for the first time anyway.

How big?

18 percent times a 25 percent increase in the Democratic margin equals 4.5 points, or a majority of Obama's popular vote margin. Had the Democratic 18-29 vote stayed the same as 2004's already impressive percentage, Obama would have won by about 2 points, and would not have won 73 electoral votes from Florida, Ohio, North Carolina, or Indiana.

So, to clarify here: Obama's youth margin = 73 electoral votes. Without the economic crisis, this would have been the difference.

In the House, the youth margin for Democratic candidates was up 18 points from 2004 and 7 points from 2006 (with a 50% increase in the voter pool from '06). The 18-29 demographic's net contribution to Democratic margins in the House went from 12% x 22% = 2.64% in 2006, to 18% x 29% = 5.22% in 2008. How many of our guys lost by 2.6% or less? And it wasn't about "more" or "new" young voters. For the most part it was the same young voters, who were conditioned to vote for Democratic candidates after switching to Obama.
