It isn't that. It's that they would waste all of the energy they've spent on uniting Americans to divide us again (yes, there are still a lot of devoted clintoon supporters) and they would not have accomplished anything useful.
Much better that they use whatever political capital they have to fight terrorism, improve education, and impose some sort of fiscal discipline. All of those are difficult, and much more useful than revenge against the smallest, pettiest people who have ever occupied the WH.
If this were ONLY about these 2 petty people, Bill and Hill, I might agree. But it is not. Its about DOZENS of high level democRATS ... infact the whole leadership of the democRAT party. Its about DOZENS of democRAT government employees, many of who are still in position where they can damage things further, who committed REALLY SERIOUS CRIMES. Unless we investigate, we won't even know how deep the ROT is, who big the pile of TRASH we have to deal with is. You can't run from crimes as serious a murder and treason. Doing so only makes WEAKER, not stronger ... only makes you more like those you despise!
