Real Clear politics has a great article by Michael Barone regarding the suddenly fluid electoral map.
The emergence of John McCain and to a lesser extent, Barack Obama (who is, after all, merely a more likeable and less hysterical liberal socialist/paternalist/pacifist) create the potential for an entirely new electoral map.
Good reading. Johnny Mac has a chance to turn Oregon, Washington, Minnesota, Wisconsin and a lesser shot at Pennsylvania, New Hampshire and Michigan. The Drama has a good shot to turn Iowa, New Mexico and Ohio, with a lesser chance at Virginia and Montana.
That much fluidity and eight months to go. 2008 might just be an eventful year.
