Georgia, South Carolina, North Dakota, Kentucky, Tennessee, Arkansas, West Virginia all have gone for McCain thus far. The only exception is New Mexico and, if all the other Bush states hold for McCain, its loss is not fatal.
We're still waiting on Florida, Virginia, Indiana, Ohio and Missouri. If McCain loses any one of those big states, though, it's all over for him. The longer and further west this race heads, the better it looks for McCain, in my book.
In the meantime, Obama has continued the 2004-repeat theme by winning Kerry's states of New Hampshire, Maine, Vermont, Minnesota and Wisconsin. Oh, and Michigan too.
