Mayoral candidate Mike McGinn issued an unusual statement this afternoon that makes several predictions about challenger Joe Mallahan's campaign activities in the next two days. Among them, Mallahan's campaign will begin criticizing McGinn's plan to extend light rail.

"We will criticize him for a lot more than that," says Mallahan spokeswoman Charla Neuman. She says the campaign has already taken odds with intent to scrap plans for a tunnel, thereby giving up billions of state funding for city infrastructure. Mallahan has also said he doesn't support the First Hill streetcar line approved last fall by voters, which McGin supports.

McGinn's campaign also predicts Mallahan will begin issuing one policy paper a week, announce a social-media strategy, and "will argue that the 70% 'no' vote on the tunnel in March 2007 wasn't really a 'no' vote."

Neuman shoots back: "No, we will tell him he has his plans mixed up and the hybrid [tunnel] option that was agreed on was not what was voted on. Tell him to read his ballot more closely next time and pay more attention to the collaborative process to reach a solutions." She adds, "His fringe positions might be why there aren't many people lining up to back him right now."

As for social media, she says that Mallahan ran viral videos in the primary election and "it wouldn't surprise me if we put up more in the general." And she says the campaign will begin issuing more positions papers.

McGinn also predicted that Tayloe Washburn, chair of the Greater Seattle Chamber of Commerce, will head the Mallahan advisory team. Neuman couldn't confirm the charge, saying, "I don't think there is a designated head person."
