Freaking out about the supertight presidential race and the near-daily barrage of polls suggesting that Obama—no, wait, Romney—could, maybe, possibly, eke out a narrow victory? Sick of empty punditry and craving data-driven electoral analysis? Are you unafraid of mysterious nerdy things like math?
If you answered yes to any of the above, check out these seven guys who crunch mountains of polling data so you don't have to. They don't have crystal balls, but they might just have the next best thing.
1. Nate Silver
The New York Times' statistics big shot has established himself as the gold standard for electoral prognostication. Romney fans are very upset with him for saying Obama has a strong chance of winning (and for being a sissy-man or something). Nail-biting Obama supporters hit his site for daily (or hourly) doses of reassurance. Both sides tend to ignore that Silver's model doesn't write off possibility of a Romney win.
Track record: Silver has built his reputation on the accuracy of his "Political Calculus": In 2008, his model correctly predicted the electoral outcome in 49 of 50 states, and long before the 2010 midterms, he forecasted a Republican sweep.
Current prediction: Silver's FiveThirtyEight gives the president a 77.4 percent chance of winning, with a estimated total of 299 electoral votes.
2. Sam Wang
Wang runs the Meta-Analysis model for the Princeton Election Consortium. Wang, who made a name for himself in neuroscience and biophysics, took the statistical analyses he'd applied in those fields and transposed them to the mess of electoral politics. He developed the model in 2004 initially to help predict the most strategic way to allocate of campaign donations. The model, based on a slew of state polls, calculates each candidate's probability of winning in the Electoral College if the election were held today.
Track record: The group behind Meta-Analysis stakes out their election prediction street cred like so: "In 2004, the median decided-voter calculation captured the exact final outcome. In 2008, the final-week decided-voter calculation was within 1 electoral vote."
Current prediction: As of October 30, Wang gives Barack Obama a generous 92 to 98 percent chance of reelection, and an estimated 303 electoral votes.
3. Drew Linzer
Linzer, an assistant professor of political science at Emory University, runs the polling analysis and forecast site Votamatic.org. It tracks public opinion trends for the two presidential candidates in each state, and also "forecasts ahead to Election Day" using a unified model.
Track record: This is Linzer's model's first real election, but he vouches for its reliability. "I validated the model with state-level pre-election polls from the 2008 presidential campaign, using the benefit of hindsight to evaluate model performance," he writes. "In a simulated run-through of the campaign from May to November, the model was able to steadily improve the accuracy of its forecasts, ultimately mispredicting the winner of only a single state. By Election Day, the average difference between the model forecasts and the actual state election outcomes was just 1.4%, with more than half of states projected to within 1%."
Current prediction: As of October 30, Votamatic is predicting an Obama victory, with 332 electoral votes.
4. Andrew S. Tanenbaum
Since 2004, this noted computer scientist and professor at Amsterdam's Vrije Universiteit has run Electoral-Vote.com, which analyzes US federal elections. Also, the site has the option of watching the election with "Rasmussen-free maps."
Track record: Click here for a self-evaluation and breakdown of the website's commendable track record since the 2004 election. Initially anonymous, Tanenbaum revealed his identity after rampant speculation that he was, among other things, "a Clinton administration official, [or] a bored retired statistician." Tanenbaum describes himself as "a libertarian [who leans] towards the Democrats."
Current prediction: With a week to go, Tanenbaum's analysis has Obama up with at least 280 electoral votes.
5. Josh Putnam
Putnam, a visiting assistant professor of poli sci at Davidson College in North Carolina, runs the Frontloading HQ blog on state polls.
Track record: Putnam was an ace at delegate math during this year's particularly messy Republican primaries. (He teamed up with The New Yorker's Ryan Lizza to count delegates).
Current prediction: Putnam's model has Obama leading with 332 electoral votes.
6. Scott Elliott
Elliott (who goes by the nickname "The Blogging Caesar") runs the Republican-leaning ElectionProjection.com, a site featuring his electoral vote formula and his own edition of "unskewing" the polls. He is a conservative political junkie who views "Jesus [as] my life and my purpose."
Track record: His track record and methods have been pretty solid—even winning him an endorsement across the aisle from Prof. Tanenbaum at Electoral-Vote.com: For instance, in 2008, his formula projected an easy Obama win, but was off by two states (Indiana and North Carolina). In 2004, his model predicted Bush netting 289 electoral votes (he ended up with 286).
Current prediction: His math shows a substantial lead for Obama, clocking in at 290 electoral votes, but with 48.9 percent of the popular vote versus Romney's 49.6 percent.
7. Thomas Holbrook
Holbrook, a professor of government at the University of Wisconsin-Milwaukee, runs the Politics by the Numbers forecast.
Track record: He took his models out for their first spin during the 2008 election, estimating a big Obama win with 349 electoral votes, to McCain's 189 (Obama snagged 365, McCain 173).
Current prediction: Holbrook gives the president an 86.69 percent chance of winning reelection, with 281 electoral votes to Romney's 257.
