What follows comes from a book review that appears in the Gwinnett (GA) Daily Post. I linked to it from Lucianne.com. Brothers Merle and Earl Black are political science professors at Emory University and Rice University, respectively. Their new book, Divided America, looks at how closely matched are the two major political parties today.
They posit that the Democrats have a 'lock' on the Northeast and the Pacific Coast, while the Republicans have a reasonable grip on the South and the Mountain Plains states. This leaves only the Midwest in true contention, with Ohio being the state upon which everyone focuses.
The brothers Black contend that both major parties are essentially minority parties, which is great for accountability but tough for governing. There is more interesting "inside politics" stuff, go here to read the whole review.
