The existence of a secret conspiracy to impeach a president should not make the president immune to impeachment.
And the Russia investigation was not a secret conspiracy. There is proof Russia interfered with our election. There is proof that Trump encouraged and welcomed Russias help in getting him elected. As a result of the investigation, there is now proof that his his campaign chairman, deputy chairman and personal lawyer all committed felonies in an effort to cover up various interactions and a Business deal with Russia. The investigation also uncovered exactly how the Russians influenced the election, the Russian individuals responsible, the servers and vpns they used, the fake identities they used, the email addresses they used, the bitcoin transactions that were made to pay for the servers and VPNs, how they got those bitcoins, the google searches the hackers made, the twitter accounts they used, and more. This information will help with protecting our election process from foreign governments in the future.
All of these things happened in the real world and have nothing to do with whether or not the president leveraged the power of his office to try and get Ukraine to help him gain an advantage in the 2020 election.
The existence of a secret conspiracy to impeach a president DOESN'T make the president immune to impeachment.
Here is the whole point. And it might sound kinda weird. But the man can be different from the person.
The person can be a man or any kind of artificial entity. Who are they trying to impeach? An artificial entity or the man?
If they impeach him, who cares? Let's take up our existence and men/women, not as persons on paperwork, and do whatever it takes to correct government from our end of things.
