The following results are based on 557 completed telephone interviews among a statewide random sample of registered voters in New Hampshire. Of the 557 interviews, 190 were among registered Republicans, 147 registered Democrats, and 220 undeclared voters. The interviews were conducted March 15 through 18, 2012.

The theoretical margin of error for the sample of 557 registered voters is plus or minus 4.2 percentage points, 95% of the time, on questions where opinion is evenly split.
