That's the problem isn't it.
Not really. If you examine the facts the Republicans are objectively and demonstrably wrong, unless the Republicans no longer believe in things like duty, honor, and country.
The President took an oath.
This was his oath:
Article II, Section One, Clause 8 - "I do solemnly swear that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States."
This is the impeachment clause:
Article II, Section 4 - The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.
This is the definition of high Crimes and Misdemeanors:
What Does ‘High Crimes and Misdemeanors’ Actually Mean? - The Atlantic
President Trump abused the power of the office of the Presiden by attempting to extort President Zelenskyy into investigating his main political rival in an upcoming election in exchange for a sale of javelin missiles. It was later found out via Sondland and Taylor that this extortion attempt eventually came to include hundreds of millions of dollars of military aid authorized by Congress. We know it was not in U.S. national interests to withhold aid to Ukraine. The aid had bipartisan support in Congress, and the DOD, per the law which Trump himself signed, was tasked with certifying whether or not Ukraine had made enough progress to combat corruption. The DOD did certify this was true. The President's NSC was unanimous about their support for military aid to Ukraine. The only people who disagreed were Trump, and his personal attorney, Rudy Giuliani. They argued that Ukraine needed to do more to combat corruption, but the only specific cases they could reference somehow happened to only concern Trump personally.
I suppose we'll just have to let this whole thing play out and whatever happens, happens.
I am very sympathetic to your approach and your political views. However, I have come to the conclusion that Trump and the burgeoning authoritarian ideology coalescing around him and his cult represent an existential threat to our Republic. When Trump's lawyers are in court arguing that Trump can never be criminally investigated because of unconstitutional ideas such as "absolute immunity" -- an idea which has no basis in our history, or laws, or the Constitution -- that's when we know they are on the wrong side of the argument.
