The D's are planning to investigate Bush to death. They are still smarting from the impeachment of their last President--a man of dubious character. [Side note: They recently ran out of their party the one Democrat with moral clarity.] Their investigations will amount to nothing, but their media accomplices will make mountains out of any molehills that might exist (e.g. Scooter Libby).
I am afraid that the D's are not taking the GWOT seriously at all. They are ostriches--hoping that it will all just go away. This is going to be a long two years.
