This past midterm election the Democrat Senatorial candidates received seven-million more votes than the Republicans, but the Republicans hold the Senate.
The Constitution of the United States has Gerrymandered the elections of Senators. Every state in the U.S. gets two Senators. North Dakota with one-half million population gets the same number of Senators as California that has 39 million population;
½ Million = 2 Senators
39 Million = 2 Senators.
There are more Red States than Blue States and with the Cult following of the party of Donald Trump, the Senate will for the future likely remain in the hands of the Republicans.
With the Senate in Republican control the chance of impeachment of Donald Trump, regardless of his crimes and misdemeanors, is zero. The Republican Senate is still in control of appointments of judges, including for the Supreme Court, and the confirmation of any Trump appointments.
It seems we are now down to two branches of government: the Congress and the Executive-Judicial
