Why the Stormy Daniels saga is important

Yea she's going to be around for some time

The controversy over Stormy Daniels is NOT about Donald Trump having sex with a porn star.  American voters knew they were bringing in a philanderer into the White House.

There are moral issues at the heart of this issue [as if talking morality about a thrice-married, twice-divorced, numerous-adulterer is relevant].  The bullying and abuse of power (see tweet above) are also highly problematic, of course.  But this is also closely related to governing: if a country's elected leader is so vulnerable to blackmail by a ghost of personal past (we haven't even mentioned questionable business dealings), then all of its citizens should want to get to the bottom of this, instead of wishing the problem would just go away.

A leader needs to show, and citizens need to be convinced, that he/she puts the country's interest above all else.

This is exactly the reason why transparency is a must for all public servants.
