I agree that partisanship makes the search for truth a much bigger challenge. However, if I'm ignoring my guy's faults because he's my guy, that doesn't make it right.. or me informed.
Case in point- Clinton. Most Dems have a pretty solid line on Clinton now, likable guy, philanderer, didn't run the country into an iceberg during a proseperous time. Partisan Dems say he brought about the goodwill by cutting the deficit and taxing appropriately... partisan Reps say he killed everyone he disliked and had sex with everyone he could. Neither partisan standpoint is true- they're both exagerrations. If as a Democrat I refused to believe Clinton had a wandering eye (and other parts), then I'd be a fool. And the wandering eye has no stake in the middle east!
Put it simply- the search for answers in the middle east- WMDs, terrorism, drilling rights, no-bid contracts.... should not stop short of the most powerful office in the world. Allowing the one country who HAS used WMD's in the past to run amok simply because no one else has the might to resist us is not a great world plan, and if we use our might to gain bigtime oil and middle east bargaining, it's not going to sit pretty with anyone we're not sharing the oil with. Our president should stand apart from this quagmire, not have financial interests with the defense contractors, the Saudi royals, and the overall oil market. These aren't wacky left-leaning myths, they're Bush family history... and this isn't even considering Dick Cheney!
As an obvious Democrat, I think Clinton shouldn't have banged that intern- but at least he was at work on a Sunday.
