Trump is incapable of setting his ego aside and makes every event or concern about him personally.
To win, he has to prove me wrong.
He has got to stay on message about jobs and the economy, national security, stopping illegal immigration (and emphasize ILLEGAL), the IRS, state department and Homeland Security corruption.
Of course he also needs to stick it to Hillary for her law breaking (with examples) and point out that she has no new plans for turning the economy around because she has no new ideas that differ from Obama. Her campaign is ONLY about bashing Trump and spending more to put us in deeper debt.
LOL!
