Let's not forget, Nixon didn't order the break in to the Watergate building. But he did get nailed for obstruction of justice while trying to protect his cronies.
I think, at the very least, the same thing will happen with Trump - even if there's not a clear cut case that Trump was in on the conspiracy - Trump will still get crucified for having tried to interfere in the investigation with corrupt intent.
And, beyond the Special Counsels Office, Trump still faces tremendous legal jeopardy for a whole host of issues including:
- Violations of Campaign Finance laws (with regards to the porn stars he paid off)
- Violations of Campaign Finance laws (with regards to his Inauguration Committee)
- Violations of the Emoluments Clause
- Money laundering through his non-profit Trump Foundation
- and tax evasion and bank fraud through the Trump Organisation
I'm sure I'm missing a few more - but you get the point. Trump's legal woes don't end with Mueller.
