Just five days before election day, a new KING 5 poll finds the race for governor is a dead heat, with Democrat Jay Inslee at 47 percent, Republican Rob McKenna at 46 percent -- within the poll's margin of error.

The poll conducted by SurveyUSA Oct. 28-31 finds McKenna has closed the gap in the past month, with the undecided vote standing at 7 percent. Our last poll two weeks ago also showed the race within the margin of error, with Inslee ahead by three points. A month ago, Inslee was ahead by five points in our poll.

The governor's race can be influenced by presidential politics, and our KING 5 poll finds no movement in Washington state with Democrat Barack Obama maintaining a 14-point lead over Republican Mitt Romney, 54 percent to 40 percent.

The poll also shows that the race over Referendum 74 has tightened. The referendum on same-sex marriage has 52 percent approving with 43 percent saying they'll reject. With ballot measures, undecided votes often lean no toward the end, and the latest KING 5 poll finds 5 percent saying they're not sure. Two weeks ago, the KING 5 poll had the measure leading at 54 percent to 41 percent.

Meanwhile, I-502 which would legalize some possession of marijuana stands at 56 percent approval, with 37 percent saying they would reject and 7 percent not sure.

The poll of 555 likely voters has a margin of error of 4.2 percent.

Washington Poll

The Washington Poll found the same-sex marriage referendum leading by a higher margin than the KING 5 poll found -- with 57.3 percent support among registered voters and 57.9 percent support among likely voters.

Conducted between Oct. 18 and 31, the Washington Poll surveyed 722 registered voters and 632 likely voters. The margin of error for registered voters was plus or minus 3.6 percent, compared with plus or minus 3.9 percent for likely voters.
