Two problems with the analogy—Scooter didn’t lie to Congress, and Scooter is a Republican. Clinton’s acquittal in 1999 showed that it is OK for a Democrat to lie under oath.
I do understand that Scooter didn’t lie to Congress. Nevertheless he was perceived by Fitz to have lied at some point in an official investigation, which justified an inquisition style prosecution. My point is the contrast between someone who didn’t lie, but was perceived to have lied and was brutally prosecuted, and someone who I perceive as possibly lying, but who isn’t likely to be prosecuted. And as you point out, lying is a crime if you are a Republican. Democrats are exempt from prosecution for lying.
