The small group

Bongino has it all wired.

He likes to say that these people know each other and have something to hide.  They continue to cook up scandals to facilitate their cover-up.  He calls the relief pitcher scam.  It is a baseball ball term applied to this political situation.  A manager replaces the pitcher once he becomes too ineffective and replaces him with a relief pitcher.  The situation in politics is similar with respect to the continual scandal-mongering from the Democrats.  Once a scandal is no longer useful to them politically, they cook up a new scandal.  It is from the same group of people who all know each other and have something to hide.

Why do the rest of the Democrats join in?  I'm thinking that they have made a strategic decision to rally around this small group.

Contrast that with the GOP who seem to abandon their leadership even at a hint of trouble.  Which is best?  Are the Democrats right or the Republicans?

In the Watergate case, perhaps Nixon had to go.  Not this time, though.  There was no crime, nor is there likely to be a crime in which the Democrats could credibly pursue Trump.

If the GOP would respond aggressively, they could impose a heavy price on the Democrats.  Party loyalty has its limits.  The Democrats are rallying around a criminal class.  No matter who you are, you cannot wish for a criminal class to have political power.  Nobody but the crooks benefit from that.
