The Senate won't allow Trump to be impeached. Democrats are just salty because they know Trump is going to win 2020.
The senate doesn’t have anything to do with the impeachment. That is the responsibility of the house alone. Trump is going to be impeached, that much is abundantly clear at this point. The senate are the ones that hold the trial on removal from office when a president is impeached. Obviously the senate won’t do that, so the impeachment will be mostly symbolic. Trump will become the third president to be impeached, and none of them will have been removed from office
