This post has been updated to correct an error in KING-5's original report. That report said that McGinn was unpopular among younger voters; in fact, his approval rating among voters between 18 and 34 was 39 percent.

As Mayor Mike McGinn prepares to give his annual State of the City speech at City Hall this afternoon, a new KING-5/SurveyUSA poll finds that one in two Seattle voters disapproves of the job he's been doing as mayor. Just one in three voters approved of the job he's done, and another 18 percent weren't sure.

McGinn's strongest approval ratings were among younger voters: Thirty-nine percent of those between 18 and 34 said he was doing well. Meanwhile, just 27 percent of those above 50 supported the job he's been doing.

McGinn was less popular than: the city council (42 percent approval); school superintendent Susan Enfield (47 percent); the Seattle Fire Department (82 percent); the electric utility (52 percent); Parks (59 percent); and Seattle Public Utilities (45 percent). McGinn did tie with the city department of transportation with 33 percent approval, but SDOT's disapproval rating, at 33 percent, was much lower than McGinn's.

What city departments or officials did rank lower than the mayor, you ask? Those would be SPD (27 percent approval); the school board (30 percent); and Police Chief John Diaz (30 percent).

The poll also asked respondents their opinion of last week's proposal to build a new arena in SoDo and bring two new teams, an NBA team and a hockey team, to Seattle.

Not surprisingly, while a strong majority supported the idea of bringing pro basketball back to Seattle in general (56 percent were either "very" or "somewhat" enthusiastic, similar to the percentage who said they'd attend games regularly), almost no respondents (a measly 10 percent) said taxpayers should have to foot any of the bill.

McGinn said last week that the project would be "self-financing" and that the city would get its money, up to $200 million, back from ticket sales, loan payments from the as-yet-unnamed investors, and possibly a new sports TV station.

And, perhaps confirming gender stereotypes, men were much more likely than women to believe taxpayers should be willing to pitch in for a new stadium, and women were much more likely to feel bad about getting a new NBA franchise if it means stealing another town's team.
