John Hardly,
I seriously doubt that the Dems would have ever spent over $70 million dollars investigating everything in a Republican President's past that might conceivably be construed as a scandal.   (The Republicans, before Lee Atwater and Karl Rove, wouldn't have, either)

Had a Republican President behaved with an over-21 intern the way Clinton did, he should not have been impeached any more than Clinton should have, and he almost certainly would not have been convicted and removed from office,   Lying about a personal, non-goverment-related matter is not what our Founding Fathers had in mind as grounds for impeachment.
