I didn't watch the debate. But if Republicans want the presidency, they would be way better off with Kasich than one of the 3 people who've never won an election (Trump, Fiorina, Carson). Not to mention Kasich is from Ohio, a state Republicans need to win.
Part of me thinks a traditional candidate who is stockpiling money will make a surge in January. Someone like Bush. Sandbag it now knowing the polls will change throughout the next couple months as the leaders lay out silly plans. Like Carson's 15% flat tax with no deductions.
