If these allegations are true, he should definitely be impeached after proper investigation. As you pointed out, he has also lied. Any elected Republican with a spine and principles would agree. I know it’s far into the future and not going to be easy, and may never happen. It is still the right thing to do, and our leaders doing the right thing is asking for too much today.
The GOP has no spine and has been totally corrupted under the Trump Administration. Had Lindsay Graham and GOP done the right thing from the beginning, the issue would have been actually investigated. Instead, they lied, misled, grandstands, and played the whole “fix is in.”
Even if a Democrat wins, correcting the errors of the Trump Administration and exposing the full corruption of Trump and the Kavanaugh handling is going to be a massive hurdle. The DOJ has been weaponized by the right wing. The right wing has fully backed Trump for political wins and court appointments, and Trump is a savior to the right wing base. At some point, the country needs to figure out how to defeat an entire party overrun by sycophancy, wide spread corruption, and cult of personality.
The second a newly elected Democratic President tries to look into the matters or clean up this corruption, the party sycophants and base will go insane. Fox News and right wing radio will blast the paranoid rhetoric. The president will be called a dictator, and I see the typical “right to revolution” and gun waving.
Watching the Democratic primaries, some of them have well thought out plans. But none of them have a strategy on how to address and correct these errors. I fear, tribalism, mass corruption, lying, and political weaponization like we saw during the Kavanaugh hearings will be the new normal. It is about political wins now. Such a corrupt and divided system may serve the most powerful on both sides but it will alienate average people.
I do hope America figures this out. If not, the country and all it claims to stand for will be lost.
