Fair question.
Trump seems to not be going after Hillary with the same "gusto" as he did with his opponents in the primaries, and IMHO he has to literally destroy the Clintons in order to win.
And the only way to do this is to litigate and convict them in the court of public option.
He’s doing what he needs to do.....it’s not just about destroying Hillary, he has to at the same time garner all the voters he can...many of which want to see the Presidential side of the man as he was in his Economic speech.... and this other stuff calmned down. “Gusto” is fine.....but in serious speeches he is, and will be, direct and “Presidential”.
One of the concerns of the party was that once Trump did clan it down those who are emotionally invested in Trump would not get it...and begin to be “disappointed” when he both sought out “other” voters and leaned ore left, and as much calmned his speech down.
I think he’ll have the gusto at Rallys...but you’re going to see him control the issues and focus....
