U.S. Constitution allows Congress to impeach and remove the President. The House debates and votes whether to bring charges against the President. All it needs is a simple majority in the 435 House members. The House has 235 members from Democratic Party, 197 from the Republican Party and 3 vacancies. So the Democratic controlled House can easily pass a resolution to impeach Donald Trump.
Once that is done, it then goes to the Senate for an impeachment trial. The Chief Justice of the U.S. Supreme Court presides. The Senate has 100 members. Two thirds majority vote is needed to convict the President and remove from the office. The Senate has 53 Republicans, 45 Democrats and 2 independents. It is almost impossible to get a two third majority (67 votes) to convict the Republican President Trump in a Republican controlled Senate.
The leader of the Democratic Party in the House, Nancy Pelosi, is not in favor of impeachment because it will not get Trump removed from office since the Republicans have majority in the Senate. Suppose the House passes impeachment resolution and the Senate rejects it, it will backfire on the democrats during the 2020 presidential election. Trump knows how to manipulate the media. Trump will put up a show as he is the poor victim and gain popularity and easily win the election. Also, the general public will get tired of the democrats.
What do I think? I think the democrats will talk about impeachment, but not go forward with it, until the election time next year.
Wait and see.
