Hmmm. Let's compare. Clinton had a scandal every month. Bush hasn't had any. Hillary tried to make herself a second president. Laura Bush hasn't done that. Clinton sold out our national security to China. Bush hasn't done that. Clinton never reacted in any significant way to terrorist attacks on American interests. Bush has responded resoundingly. Clinton defiled the Oval Office. Bush has treated the office with respect.
I could go on and on - but to anyone who bothers to compare the two, the reasons are clear as to why Clinton was despised by the right - for damn good reason. Why is Bush despised by the left? Because he is willing to act in the national interests of this country, something the left simply cannot stand.
Oh, and since you're comparing Kosovo to Iraq, let's look there as well. Both Iraq and Kosovo were not sanctioned by the UN - but Mike Farrell approved of Kosovo but not Iraq. Intervention in Kosovo made matters worse. Intervention in Iraq will, in all likeliehood, make matters better for Iraqis. And, most importantly, Kosovo had no bearing on this country's national interests and security - but Iraq does.
Only the shallowest of thinkers try to draw moral equivalence from superficial similarities.
