“Your election is in the public interest. And if a president does something which he believes will help him get elected in the public interest, that cannot be the kind of quid pro quo that results in impeachment.” - Alan Dershowitz 1/29/20
A sitting President who in his/her capacity as President says his/her election is "in the public interest" is free to do whatever s/he wants to get re-elected. That is Mussolini in spades.
And if the Republican majority in the Senate agrees with this by acquitting this President...the Legislative Branch of this government has effectively gutted itself when it comes to it's former Constitutional power and responsibility to intervene when a President has abused the power of the office.
If I haven't recommended this for reading before, I'm doing it now.
