I finally figured it out! The Republican Party allows Trump to stay in the race so another candidate appears terrific! It's a scam. Would be like me showing up to a formal affair in secondhand clothes and another person shows up dressed in rags. I will look marvelous in comparison. Seriously, Trump is a TV show personality who has his followers mesmerized by his being a famous person. Not too many people would even recognize their senator if he/she showed up at their front door.
