Wow ! You see much that isn't there. How are the Republicans "destroying and dismantling the founding principles of the country" ?
What "dire implications for the governance of the nation" exist ?
By the Constitution, the democrats impeached the president, and by the Constitution, he will not be removed from office.
The democrats haven't come close to showing any foreign power linked to Trump. If they had, it would be a crime, and they would have used it in their articles of impeachment. They did not.
You don't like Trump, perhaps with very good reason. Yet repeating as fact that, what cannot be proven is of no real import,
The democrats hate Trump, because of that hate they started looking for a reason to impeach him on inauguration day.
The Constitution no where states that one party can dispose of the president of another party because they hate him.
The standard is bribery, treason (both statutory crimes) or OTHER (meaning statutory crimes) high crimes or misdemeanors. The democrats haven't produced statutory crimes in their articles. What they have produced are non statutory, that are crimes because it is their opinion they are crimes. It is your opinion they are crimes.
It is the Republican opinion they are not crimes, it is my opinion they are not crimes, the Constitution makes clear they are not crimes. Because Trump committed no crime, he will be found not guilty.
