Searches on Roe v. Wade, Joe the Plumber spike during debate

Google had a nifty idea: Track the search patterns of its users during last night's final presidential debate.
While hardly scientific, its observations offer interesting insight into the interests of voters.
Surprisingly, the biggest spikes in user interest came during discussions about of abortion and education. Searches on Roe v. Wade and charter schools saw a spike in activity.
Sen. John McCain's ceaseless criticism of Sen. Barack Obama also prompted plenty of searches on U.S. Rep. John Lewis, ACORN, former Alabama Gov. George Wallace, Obama's tax plan, and anti-McCain T-shirts.
The oft-mentioned Joe the Plumber also generated interest.
