If you can't impeach someone who lies to the FBI & who has clearly tried to obstruct an investigation then you're saying a person should be above the law if he has enough power. Your entire constitution becomes toilet paper & your Republic meaningless, existing in name only.
1998?
A. Impeachment did occur in 1998. Clinton was simply acquitted.
B. Literally none of those things listed occurred or were committed by Clinton in any way related to his impeachment, or arguably at all during his administration. He had some ethical issues to be sure, But none of those things were involved.
Once again, reality and you are quickly divorced.
It was perjury in 1998, that was the sole issue; had Clinton bluntly admitted it, there would have been no impeachment. Slightly before leaving office, Clinton had to surrender law license, and pay a hefty fine, on this issue.
Not even Mueller has suggested that Trump lied to the FBI.
Then again the fact that he repeatedly solicited multiple crimes is interesting. The politics might be different because it really more directly relates to what is happening and he is arrogant and not ashamed of embarrassed of his actions.
