Fresh off a two-day swing to the Pacific Northwest, where he talked up his climate change plans and focused on the importance of the environment, John McCain wants you to know he's going green, and he wants you to join him. "This week our campaign is promoting John McCain's long-term commitment to providing market-based solutions to climate change and highlighting ways we can all protect our environment," campaign manager Rick Davis emailed supporters yesterday.

But that's not all: "We're also taking this week to launch a new section of our store - complete with eco-friendly items."

Fill those Chirstmas stockings early with an embroidered polo shirt or t-shirt, 70% of which is bamboo and the other 30% of which is cotton. Take your support to the grocery store, with an organic cotton tote bag woven in the United States. And it's never too early to head back-to-school shopping, especially not with a recycled notebook with pages lined and colored with organic-based inks.

On Monday, McCain gave an address on climate change in Portland, and even the state's Democratic governor, Ted Kulongoski, showed up to take a listen. Yesterday, McCain went to North Bend, Washington, just east of Seattle and at the foot of scenic Mt. Si, to continue touting his green plans and to take a quick hike in the woods (an outing that traveling press secretary Brooke Buchanan looks very unhappy with, as Jonathan Martin's photo shows).

Had he been wearing one of his new shirts, McCain might have rethought wearing them. What's the point, Politics Nation is left to wonder, of wearing a shirt that's biodegradable? Wouldn't it just fall off? Such environmentally-conscious fashion considerations are not exactly our forte. Perhaps it's time to invest in a biodegradable polo shirt.
