Is this the beginning of the end of the Trump administration?

Nothing good ever happens, so no.

~Six months from now, will there be any Democratic Senators calling on Trump to resign, and who will they be?

I think you left out the word "not" here.

I think people are getting ahead of themselves here.  Right now, AFAIK, no prominent Democrats are calling on Trump to resign.  They're calling for an investigation.  "Investigation" can last for months/years, so it's not clear to me how far things will have actually advanced by the fall of this year.

Things move quickly in the Trump era

Including the markets..........The Dow closed at another all time high.  

maybe all the scandals are making investors confident that Trump won't be there long

Someone always makes money when people are being dumb. Maybe I will. All I know is that because there isnt really a jumo in productivity, this is going to suck when in pops.
