Survey of Likely Voters in Early Primary States
This document includes detailed results from a November 2007 Kaiser/Harvard survey of likely primary voters in 35 states (and the District of Columbia) with January or February 2008 primaries or caucuses. Data from the survey was published in the Jan. 24 New England Journal of Medicine as part of an analysis by Harvard and Kaiser researchers.
The survey was conducted by telephone November 1-11, 2007 before any primary elections had occurred, in order to reflect voters’ initial views on the issues. The survey included 674 self-reported registered voters who said they were likely to vote in their state’s Democratic primary or caucus, and 508 voters who reported they were likely to vote in the Republican primary or caucus. The margin of error for likely Democratic primary/caucus voters is plus or minus four percentage points, and plus or minus five percentage points for likely Republican primary/caucus voters.
