if you notice, I said "before April", that is when those Republican votes that Obama got (2:1) really hurt Hillary. There is no question that the Obama people (much as they're loathe to admit it) benefitted a great deal from the animosity of the right wing media toward Clinton and treated Obama as their champion to slay the dragonlady.
Clinton got far, far more right-wing votes in Texas than Obama did, and Mississippi as well. Exit polling is extremely clear on that. It's possible that Operation Chaos was the entirety of Clinton's popular-vote majority in Texas. Both of those contents were before April.
The news channel most favorable to Clinton since mid-February has been FOX News -- enough so that Clinton's campaign has loudly praised FOX. I thought FOX News was the epitome of the right-wing media? Bill Clinton went on Limbaugh's show to try to get people to vote for Hillary -- is Limbaugh no longer the right-wing media? Scaife, right-winger to the core, endorses Hillary? And so on, and so on...
The right-wing media has been in the tank completely for Clinton since mid-February. There's case after case of exactly that. Numerous right-wing pundits have said positive things about Clinton -- or, in some cases, negative things, but urged voting for her anyway. I have yet to see any major right-wing pundits saying much in the way of anything positive about Obama.
