I haven't seen it announced that trumptv is a certainty, more of a goal.
It would be somewhat shocking if he really didn't want to win, hes seems like an egomaniac. Winning would be his ultimate goal.
I'm sure he's a little surprised he's in this spot. Money and wealth is power but becoming President transcends all the money in the world.
You may be right though....
his lifestyle is great. he's a ribbon cutter. reading briefs and making boring decisions 14 hours a day is not for him. He already said his veep would handle all of the day to day stuff, he'll just cut ribbons and 'make america great'. Look it up. He said his veep will have most of the duties. that is unprecedented.
I cannot assume 'winning' is defined as the presidency... a stressful 4-year job he's kinda not prepared for.
Maybe 'winning' = a massive tv network to rival FOX/MSNBC, with his kids running it... a Billion dollar tv empire that'll last for generations with his kids being stars. IMO, to a 70 year old that loves his family, a billion dollar network that'll last 50 years WAY outweighs a 4 year stress filled job where 2/3 of the country is always hating on you anyway.
