At least 8 of the questions were from Democratic activists planted to embarass the Republican candidates. One of them, the gay retired general, is on Clinton's campaign committee and had actually been on CNN before. No question that CNN should have known of them.
The previous CNN moderated Democratic debate had at least 6 Democratic activists as their supposedly unbiased panel of questioners.
In my opinion these so-called debates are debasing and corrupting the presidential selection process.
