The blunt answer is for lying about receiving blowjobs from a consenting adult not his wife. How many married men would want to publicly announce that to the world? In fact, some of the same Congressmen who impeached President Clinton were exposed as also having adulterous affairs with women not their wives. That is why I find it so hypocritical when I hear someone like Ken Starr (who prosecuted President Clinton) defending Trump*. Lying about blowjobs is not the same as jeopardizing our national security to rig a presidential election. That is also why I find it extremely hypocritical when I hear Trump* supporters talking about "payback" for impeaching Trump*. If anything, Democrats deserve some "payback" for what Ken Starr did to President Clinton. However, the Trump* impeachment is not about "payback". The Trump* impeachment is about exactly what the House impeached him for: Abuse of power and Obstruction of Congress. In short - for trying to rig the 2020 presidential election.
