“If he doesn’t convince them do they have any right before the convention to refuse him as ‘their’ Representative??????”
No right whatsoever. The primary voters have spoken. It’s why we have primary elections: to allow the people to choose who they want to run for President. And they’ve chosen Donald J. Trump.
It’s THEIR party....you’ve simply chosen to be a member of....I want to know if they have that right....just because you continue to see what you want to see doesn’t make it so.....which is certainly why I didn’t address you with the question rather one who has handle on the election process.
