The sincere problem with a lot of this speculation continues to be the assumption that 2008 will be a lot like 2006, an assumption just as problematic as the assumption in June 2005 that 2006 would be a lot like 2004.
Since I've been cleaning up the forum of late and reading through threads from this era, the comparison is highly enlightening.
Definitely words to the wise there. Especially for those predicting landslide Democratic victories. There really is no way for anyone to say with certainty what 2008 will look like. 18 months is a long time. Who knows what will happen to the world during the next year and a half. However I do think the Democrats definitely have cause to be optimistic at this point in time.
