Another reason to hope Trump snubs them. Ratings will suck without his draw.
Yes the ratings will suffer some without Trump to draw in their audience, but I for one am looking forward to watching a debate on the issues (hopefully) rather than insulting one another. I don't want to watch Trump's bullying and theatrics. I've had enough.
Guarantee though, if the candidates take aim at Trump during the first debate without him being there, he'll make it to the second one.
