Nancy Pelosi is frustrated and she has every right to be with the radicals in her caucus. Say what you will about Nancy, she is cagey and ruthless and quite good at her job. So she must be sitting back in horror as her colleagues in the House rush headlong over the cliff of impeachment. For sure, Pelosi can step in and stop it at some point but if momentum continues to build in the Dem party she will not be able to stop it without disenfranchising the base.
