President Barack Obama has a 51% chance of being elected, according to the Intrade market, in which bettors buy and sell shares that pay off if their predictions are correct. How accurate is the collective wisdom of the market on political matters? More accurate than political pundits, according to the Washington Post and the New York times. http://tierneylab.blogs.nytimes.com/2008/11/24/bettors-beat-pundits/
While the Intrade market has been a more accurate barometer than public opinion polls, its data only occasionally gets used in news graphics, such as the New York Times chart above.
To read Intrade data as a percentage, you just convert the dollar amount so that, for instance, $6.70 is 6.7%.
In addition to a market on Obama’s chances, Intrade has odds on each GOP presidential candidate, House, Senate and Governors’ races, and whom Sarah Palin and Jim DeMint will endorse.

For years, the Washington Post has produced “inner circle” charts that portray the individuals surrounding powerful political figures, such as President Obama, Hillary Clinton, and now Republican Leader John Boehner.
The diagrams show levels of influence as concentric rings, and categories, such as staff or college classmates, as wedges of the circle. The graphics reporter assembling the diagram needs a deep knowledge of the politician in order to assign a level of influence to each associate. The connections and coalitions are equally hard to arrange and often require reliable sources near to the politician to help with the placement.
The final trick is to get photographs of the dozens of people in the diagram, many of whom may be obscure despite their connections to powerful people.
