The following results are based on 541 completed telephone interviews among a statewide random sample of registered voters in New Hampshire. Of the 541 interviews, 162 were among registered Republicans, 158 among registered Democrats, and 221 among undeclared (independent) voters. The interviews were conducted March 14 through 17, 2008.

The theoretical margin of error for the total sample of 541 is plus or minus 4.2 percentage points, 95% of the time, on questions where opinion is evenly split.
