The impeachment process could legitimately exist in the past because the two party system in America functioned. The two party system consisted of roughly equal numbers of liberals and conservatives in both the Democratic and the Republican Parties and their members were strongly pro-American. The functional political relationship of members of both Parties to each other at that time was one of attractive opposition. Under these conditions, members of both Parties were able to work together cooperatively for what was in the best interests of America.
With the anti-authoritarian transformation of American society and the shift to the left of center in American politics, the relationship of the two party system changed and became one of antagonistic opposition. Members of the two Parties could not work together. This was because the Democratic Party became riddled by and under the control of leftist ideologues. Their anti-American agenda for that Party became to destroy the American nation in every way possible. For example, the Impeachment process that is being brought up against President Trump has nothing to do with criminal charges. These are being concocted and promoted in the hope that the public will sooner or later buy into them. The longer that they can keep their false accusations alive in the media and the longer they can repeat them, the better are the chances that they will succeed in destroying the American system of government.
Even if these far-left emotional plague characters do not succeed in destroying America today, their chances in the future for another, new tragic communist takeover will be greater because the infestation of the emotional plague will have spread further in the Nation.
