HARRISBURG, PA — A recent poll has Republican Gov. Tom Corbett pulling within single digits of challenger Democrat Tom Wolf. The survey says Wolf would win the race, with 42% of the vote, while Corbett would gain 33%.
But the gap is much narrower than that shown in other polls. Part of the reason may be that the CBS/New York Times poll was conducted by YouGov and includes only people with a connection to the Internet, which excludes about 20% of residents in the United States.
A statement on the YouGov website says, “YouGov has created a panel of over 100,000 registered voters who will be interviewed four times between July and November for the nation’s newspaper of record and premier television network. The panelists come from each of the 50 states and 435 congressional districts. They are interviewed on the Internet and have been weighted to be representative of registered voters in each congressional district using data from the U.S. Bureau of the Census and other sources.”
