Am thinking GOP and Corporate Money are playing up Clinton over Sanders because they do not want to run in general election against Bernie. I suspect they are holding back on tough attack (very negative stories of Clinton's character and veracity) so that she will win Dem primary and they won't have to face Bernie, who has no known dirt hiding in the closet. They may possibly win the presidential election if they have a large arsenal of dirt to reveal about Clinton prior to the Nov election. Carl Rove and friends will undoubtedly have a lot of ammo.
Also, what's with Google news coming out with a poll being published today that was taken prior to last Saturday's results in Washington, Hawaii and Alaska that shows California democrats saying they will vote for Clinton? That is not news. It is being presented as news that is intended to play with the facts to give Clinton some favorability. Google is a GOP tool.
