Why is the vote necessary? Is it because we're moving forward with the process?
No. The Dems aren't moving forward with the "process"...they are running this alleged inquiry like a Russian show trial.
Here is why the vote is necessary.
Impeachment proceedings may be requested by a member of the House of Representatives on his or her own initiative, either by presenting a list of the charges under oath or by asking for referral to the appropriate committee. The impeachment process may be requested by non-members. For example, when the Judicial Conference of the United States suggests a federal judge be impeached, a charge of actions constituting grounds for impeachment may come from a special prosecutor, the President, or state or territorial legislature, grand jury, or by petition. An impeachment proceeding formally begins with a resolution adopted by the full House of Representatives, which typically includes a referral to a House committee.
The type of impeachment resolution determines the committee to which it is referred. A resolution impeaching a particular individual is typically referred to the House Committee on the Judiciary. A resolution to authorize an investigation regarding impeachable conduct is referred to the House Committee on Rules, and then to the Judiciary Committee. The House Committee on the Judiciary, by majority vote, will determine whether grounds for impeachment exist (this vote is not law and is not required, US Constitution and US law). If the Committee finds grounds for impeachment, it will set forth specific allegations of misconduct in one or more articles of impeachment. The Impeachment Resolution, or Articles of Impeachment, are then reported to the full House with the committee's recommendations.
The House debates the resolution and may at the conclusion consider the resolution as a whole or vote on each article of impeachment individually. A simple majority of those present and voting is required for each article for the resolution as a whole to pass. If the House votes to impeach, managers (typically referred to as "House managers", with a "lead House manager") are selected to present the case to the Senate. Recently, managers have been selected by resolution, while historically the House would occasionally elect the managers or pass a resolution allowing the appointment of managers at the discretion of the Speaker of the United States House of Representatives. These managers are roughly the equivalent of the prosecution or district attorney in a standard criminal trial. Also, the House will adopt a resolution in order to notify the Senate of its action. After receiving the notice, the Senate will adopt an order notifying the House that it is ready to receive the managers. The House managers then appear before the bar of the Senate and exhibit the articles of impeachment. After the reading of the charges, the managers return and make a verbal report to the House.
https://en.wikipedia.org/wiki/Impeachment_in_the_United_StatesNone of what is quoted above has been done to this point and even Pelosi's resolution that might or might not be voted on tomorrow doesn't cover any of this.
There's this thing called "due process" that even the President is entitled to despite what you Progressives might think.
And so far with all the secret Star Chamber closed door bullshit being done by your fellow Libs none of that is happening.
The proper House committee isn't even in charge of any of this.
That is why the vote is necessary. And it's why Pelosi has dodged it and continues to dodge it because she knows they don't have the votes in the full House for a formal vote on impeachment.
