Survey USA: Murray 37%, Rossi 33%, Didier 5%, Akers 3%

A new KING 5/Survey USA poll has Patty Murray and Dino Rossi far ahead in the August 17 primary for the U.S. Senate race in Washington state:

Murray (D) 37%
Rossi (R) 33%
Didier (R) 5%
Akers (R) 3%
Undecided 19%

The poll's margin of error is 4.4%, which means Murray and Rossi are statistically in a dead heat.  These results are almost identical to an Elway poll released last week, which was the first poll conducted specifically of the August "top two" primary for which ballots will start being mailed out in a about a month.  38 of 39 Washington counties are all vote by mail.  The top two vote-getters, regardless of party, will go on to the November general election.

The poll also verified the "enthusiasm gap" between Washington Republicans and Demoocrats:

Meanwhile, a good sign for Republicans is voter frustration with the status quo. The poll asked voters how enthusiastic they are about voting this year compared to last year. Among Republicans in our state, 49 percent are more enthusiastic this year. By comparison, the majority of Democrats, nearly 60 percent, say they are no more or less enthusiastic than usual.

Who could be inspired by voting for Patty Murray's 19-24th years in the U.S. Senate?  What have the first 18 accomplished?
