Much ado about nothing.

The Trumpenproletariat are apoplectic because the Democrats tried to find negative information about Trump?

So what?

Nothing illegal or unethical here.

The truly interesting thing about this dossier is that it was originally contracted for by one of Trump's primary opponents, a "Never Trumper", (probably a Jeb Bush super-pac) before the Democrats got involved:

"When Fusion approached Elias, it had already been doing research work on Trump for a client during the GOP primary. 

The identity of the original client has not been revealed."

But it will be, and it will tear the Republicans apart at an even faster pace than they're now ripping each other.
