Suppose the House impeached Trump, could McConnell...

[Archae]

Do like he usually does and block any votes on it?

[Buckeyeblue]

2. There is nothing in the constitution mandating a Senate vote

The constitution only says that the House can impeach and the Senate can convict. There is no time table mandated. Which further strengthens Pelosi's position that impeachment needs to be a bi-partisan exercise.

3. Why would he block a vote?

In all likelihood, there wouldn't be enough votes for conviction.

[Buckeyeblue]

8. I'm not sure that he would

But constitutionally I don't think he has to.

4. there is no vote until the trial is done, could McConnel block a trial? With political peril bigtime

sure....
places GOP senators even more at risk as being lackeys of trump and not senators for their states

[beachbum bob]

5. Such a move by McConnel would make Pelosi even more powerful as she does control the MONEY

and she could legitimately do things to force Mcconnel to his knees if the American people are behind her

6. No.

[onenote]

7. No.

There are specific Senate Rules (only changeable by a 2/3 vote) governing impeachment trials in the Senate. Under those rules, once the House adopts articles of impeachment, chooses managers for the trial and presents the articles to the Senate, the Senate is required to convene at 1 pm the next day to begin consideration of the impeachment and is required to continue to consider the matter until a "final resolution."

While the defense could slow roll the process by calling an endless stream of witnesses, in the end a vote will happen. Consider also that the trial will be presided over by Chief Justice Roberts. While I'm no fan of Roberts, he's demonstrated a few times that he understands history and is concerned enough about his own legacy as to not make a shambles out of a process (presidential impeachment trial) that has only occurred twice in the nation's history.
