registered voters. Now, other polls have Obama ahead of Romney or tied in swing states. Are polls this far from election day good predictors?

Former Massachusetts governor Mitt Romney leads the president 50%-46% among registered voters, Romney's strongest showing against him to date. Obama edges former Pennsylvania senator Rick Santorum by a single percentage point, 49%-48%."
The poll of 1,014 adults, including 898 registered voters, has a margin of error of plus or minus 4 percentage points. The error margin for the sample of 481 Republican and Republican-leaning independents is 6 points.
