Pointless argument and comparison.
Even though we consider the Russian collusion stuff, and all the accusations thrown at Trump for the past 4 years, were allegations and claims they nevertheless triggered investigations.
No matter they were completely fabricated hoaxes with no fundamental merit or basic standing.
Or, even more absurd, the Kavanaugh rape allegations. Unsubstantiated, uncorroborated, unsupported. And yet! Yet "we must believe the accuser!" and "the accused must submit himself to the inquisition!". One person made a claim. One! Only one. And everybody come running alongside her.
Yet, these "what if" got treated seriously. After all, if a claim is made it should be looked into?
These are the precedents, among countless others, that were set.
And yet, here we are. Countless affidavits, witnesses, evidence, corroborated testimonies, hours of hearings, etc... private citizens coming forward, political figures supporting the case, lawyers, legislators, constitutionalists pleading.
But, for some reasons, it does not meet the threshold. For some reason it is summarize as "Trump's ego".
Same goes with comparisons that ought not to be made to begin with: French elections vs US elections.
Two very different systems with one much more complicated than the other.
