As reported in this article, Ralph Nader is beginning to search for a primary challenger to President Obama. While I happen to agree that the President is facing an uphill battle to re-election, nothing would guarantee a Democratic defeat, no matter who the Republican nominee might be, so much as a slit amongst Democrats.
If one does not want a President Bachmann, and I don't, then Democrats must stand united. Even if they are defeated, Democrats could do our country a great service by running a hard campaign that forces the Republicans to moderate their choice of candidate.
Of course, if the economy, especially unemployment gets worse, Obama is toast no matter who runs against him.
