Well, welfare reform, balancing the budget, and the great ecomonic steps our nation made weren't Clinton's fault, but he took quite a bit of credit for them. The middle-east situation's ups and downs weren't really his fault either, but he got a lot of credit for them. Eastern Europe was as troublesome as usual, and he got some credit/blame for those issues.
But if you're talking about all the issues that came up regarding Clinton's personal life I think they're mostly irrelevant to his actual legacy. On the other hand, those issues kept the public thinking about the President's personal life and a minor symbolic legal slap on the wrist instead of the many much more important (and questionable) things that were going on both domestically and abroad. It wasn't like he was any more or less of a man-whore during his 2nd term, but since he couldn't be re-elected and there was no situation where he'd actually be hurt in any important way by the proceedings it was in his (and everyone's) best interests that he be publicly villified by people who hated him anyways.
