It's politics, and when there is blood in the water a feeding frenzy ensues. The best thing here for the GOP- a swift and early resignation from Trump. Otherwise this becomes a constant theme in the liberal media, and the Dems make huge gains in the mid-terms. This is having a crippling effect on their GOP agenda. If Trump were gone tomorrow, so to speak, Pence will have the opportunity to establish himself, and prove he is either a good POTUS or not.
Trump resigning is the absolute worst thing he can do. If he does every time there is a Republican that Democrats don't like they will create a boogeyman and force them to resign.
The best thing that Trump and Republicans can do is do what the people sent them to DC to do: repeal and replace Obamacare root and branch and tax cuts.
If the Democrats keep up with this outrage everyday they will lose unless the Republicans don't ram every thing down Democrats throat.
Normally I would concur with your sentiment. However the fact, or the alleged fact, that Trump asked Comey to drop the Flynn investigation does at least hint of obstructionism. Now follow that with Trump firing Comey and it really begins to smell. Let's see who Trump appoints as the new FBI director and what becomes of the Flynn investigation. If the rank and file at the FBI, who by most accounts supported Comey, make noise about the investigation being killed with a new Director, then we are going to be in a very serious state. IF we have a major branch of the DOJ, the FBI, being politically active things have to change.
