A national poll shows the race between Republican Deb Fischer and Democrat Bob Kerrey has tightened, but it is a poll that undersampled Republicans and oversampled independents.
Pharos Research Group, a little-known polling company that has released few public surveys, released a poll this week that showed Fischer ahead by about 2.5 percentage points.
The live telephone poll surveyed 783 likely voters and had a margin of error of about 3.5 percentage points. It was conducted between Oct. 19-21, according to the Pharos Research Group.
The pollsters interviewed fewer Republicans than the percentage of registered GOP voters in Nebraska. They also talked to a lot more independent voters.
About 43 percent of the poll's sample came from those who identified themselves as registered Republicans. In Nebraska, about 48 percent of the state's registered voters are Republicans.
About 26 percent of the poll's sample came from registered independents. In Nebraska, about 19 percent of the state's registered voters are independent.
The poll's Democratic sample was almost on the mark. It sampled 31.4 percent of registered Democrats. In Nebraska, about 32 percent of the state's registered voters are Democrats.
