I do not think so. The fact that 10 people are running for the Red nomination tells you a lot of people in politics think Trump will not make it. Those are Repubs. Running for president is not fun and is a lot of work. They are there because they are sure Trump will not be.
No telling about the future, but my bet is that Trump will be the nominee of the Republican Party.
We'll see.
The fact that he currently is far and away the favorite for that position tells you everything you need to know about the base of the Republican Party.
