The Trump Effect: The young Republicans frustrated by presumptive nominee
Much has been made in this campaign of the success of a 74-year-old Democratic socialist in attracting young voters, but for many Republicans this was supposed to be the year that their party became "cool" among younger voters.
With two leading candidates in their 40s (Senators Ted Cruz and Marco Rubio), and another generation rising up the ranks, there was hope that a similar groundswell of support that swept Barack Obama into office eight years ago would play out on the Republican side.
That was not to be.
Three young Republicans tell the BBC's Barbara Plett-Usher why their party missed the boat on attracting voters like them, and why the presumptive nominee doesn't represent their values.
