Was the impeachment really a Republican vendetta?
How else could one read it?
As soon as the Republicans took power, they appointed Kenneth Starr special prosecutor. But then, the charge against both Clintons was supposed to be murder, pursuing the allegations that Bill Clinton abused his power as state governor to kill a man and cover it up in relation to Whitewater. Or at the very least prove serious criminal wrongdoing by the Clintons in Whitewater, or anything whatsoever they could find to stick to him.
All they had in the end was Clinton perjuring himself about something they had no sensible business asking about in the first place.
Clearly there was a mixture of a passionate hate for the Clintons, or anyway a deep sense that Clinton was not a legitimate President, combined with a desire to counter the legacy of Watergate by proving the Democrats were exactly as corrupt as Nixon.
What would you say it was, if not a vendetta? Sincere shock that a President might have a sexual affair while in office? Sincere concern for the dignity of Lewinski? Concern for Hillary Clinton? (They were trying for her head just as much as her husband's, she and he were equally purported to be liable in the allegations of criminality that were the premise of the Special Prosecutor's mandate).
