This is not to be the temporary triumph of a political party, but is to endure in its consequence until this whole continent shall be filled with a free and untrammeled people or shall be a nest of shrinking, cowardly slaves.

This impeachment set an odd precedent for future presidentsSource: Pinterest
Once set the example of impeaching a President for what, when the excitement of the hour shall have subsided, will be regarded as insufficient causes, as several of those now alleged against the President were decided to be by the House of Representatives only a few months since, and no future President will be safe who happens to differ with a majority of the House and two thirds of the Senate on any measure deemed by them important, particularly if of a political character. Blinded by partisan zeal, with such an example before them, they will not scruple to remove out of the way any obstacle to the accomplishment of their purposes, and what then becomes of the checks and balances of the Constitution, so carefully devised and so vital to its perpetuity? They are all gone.
