There was no shortage once again on cable and elsewhere in which pundits were asked how the midterm election would come out, something that of course by its nature was unknowable in advance. The general consensus among political prognosticators was that Nov. 7 was going to bring Democratic gains in Congress. Among a group of the most widely quoted election oracles, no one hit exactly what the final House tally appears likely to come out, but one prognosticator got very close.

The final tally from the mid-term election is in—you know the poll in which people actually vote—and the media polls can now be graded. With each election, there are more media outlets, and more polls. Usually, the polls begin to converge as election day nears. This year, the polls varied widely. How did they stack up against the actual vote?

As 11 p.m. neared on November 7 and the networks were about to sign off, NBC projected the Democrats would take control of the House though the results of many races were still out. It soon had company. In the next 21 minutes, all the networks and cable channels made their calls as well on what was still a fairly fluid map. This was the most the networks would do on a difficult night.
