(CNN) - Voter anger at current conditions in the country right now and at the Democrats' agenda in Washington helped fuel the upset victory of Republican Scott Brown in Tuesday's special senate election in Massachusetts, according to a new poll.
The survey, conducted right after the Tuesday election by the Washington Post, the Kaiser Family Foundation and Harvard University, was released Saturday morning.
Nearly two-thirds of Brown voters questioned in the poll say that their vote was partially to express opposition to the Democrats agenda in Washington. And three-quarters of people who cast ballots for Brown, a Massachusetts state senator, say they are dissatisfied or angry with the policies of President Barack Obama's administration.
Brown narrowly defeated state attorney general Martha Coakley in the special election to fill the last three years of the term of the late Sen. Ted Kennedy. Brown became the first Massachusetts Republican to win a senate election since 1972. Brown's victory in a state where Democrats win most elections, preceded by GOP victories in gubernatorial contests in New Jersey and Virginia last November, appear to have put the Democrats on the defensive.
The poll indicates that independent voters made up about half of the electorate in Tuesday's election in Massachusetts, and that Brown topped Coakely by around a two to one margin among independents. Exit polls from 2008 indicate that Barack Obama won independents in the Bay State by 17 percentage points over John McCain in the presidential election. Exit polls from November's contests also indicate that Republicans won the independent vote in New Jersey and Virginia.
The Washington Post, Kaiser Family Foundation and Harvard University poll was conducted January 20-21, the two days following the special election, with 880 people who voted in the contest questioned by telephone. The survey's sampling error is plus or minus 4 percentage points.
