I would like to preface this by saying that this election is not yet a forgone conclusion. There are still many things that Democrats can do to lose this election. It is imperative that we do not get overconfident.
Having said this, I think that we can all pause and take a brief sigh of relief to recognize that eight years of the worst presidency ever is almost over. I must admit that in one major way however, (brace yourself for this) that George W. Bush , the unequivocal worst president in United States history (in my oh so very humble opinion) has been good for the democratic process in this country by unintentionally causing a necessary split in the Republican Party (I know it may not sound like a big deal, but stick with me on this one).
What the Republicans are left with is the group that has been a destructive force for American democracy since their emergence as a major political force in 1980: the "moral majority" (because, of course, they are more moral than those horrible people known as democrats), now better known as evangelical voters. George W. Bush won the election in 2004 by mobilizing the right wing evangelicals and alienating everyone else; John Kerry lost the election by doing essentially the same thing.
With Bush's approval ratings so awe-inspiringly (and kind of amusingly) low, McCain will not win by concentrating only on the base. McCain has been given the impossible task of uniting the Republican Party that Bush divided. Bush furthered democracy (unintentionally, mind you) by dividing the Republicans into the two parties that they really are: the right wing religous nuts, and the understandable fiscal conservatives.
This correction that George W. Bush has made to the Republican Party will change the way Washington works for the better. Republicans from more civilized states (yes that wording is intentional) will feel more comfortable voting against old party lines in such non-issues as gay marriage and flag burning while being champions in understandable goals such as cutting spending and reducing the national debt.
For this reason, George W. Bush, who came into power in 2000 in spite of losing the popular vote (and possibly the actual election), suppressed the rights of gays and other minorities, increased the national debt to unprecedented and unimaginable figures, and performed favors for the rich while throwing the less fortunate into the streets, is the best worst president any country could ever hope for.
Many thanks, Governor Bush (as George Carlin put it, governor is the last position he held legally) for being so incompetent, uninformed, out of touch, and in many cases just plain lazy during your eight long, painful years in office. Through your failures, America has learned much about what they really need in a president, and, most importantly, that they should never elect someone like you ever again.
