In the broad story that was turnout, this is perhaps the most important chapter.
In the home stretch, the Romney campaign pointed to a big jump in voter contacts this year over John McCain's 2008 effort. But a significant percentage of the voter contacts they pointed to included indirect contact -- like door hangers -- that didn't give voters the all-important sense of personal connection.
Meanwhile, the Obama campaign's turnout effort flooded the zone. While Republicans were still battling for the nomination in the spring, the number of Obama field offices in key primary season states likely to play significant roles in the fall -- states like Ohio, New Hampshire and Florida -- already outnumbered those of all his potential GOP challengers combined, even though the president wasn't facing any primary season challengers.
