In my opinion, the public elected Trump to fight against class warfare - separate rules for the elites, crony capitalism, the Deep State, etc.
If Team Trump has made the decision to let the Clinton email scandal slide under the rug in hopes of not stoking the fires of anger any further they're making a huge mistake. The fires are already rampaging all across the country and the arsonists on the Left are out there lighting a new one each and every day. Ignoring one fire and hoping it goes out all by itself will not dampen down all the other fires one single iota. Pissing on a single tree during a forest fire is a fool's errand.
And you don't want to risk loosing supporters now when now is the time to stand and deliver.
