I'm pretty pissed off at the news media's handling of things lately. They're obsessed with Trump and basically only talk about him unless someone else suddenly "surges" in the polls. Even when other candidates come up, it's mostly to respond to whatever he's been saying lately. There are still 13 other Republican candidates, three Democratic candidates, and even two third-party candidates who have sufficient ballot access that they could amass the 270 electoral votes needed to win.
In reality, Hillary Clinton and Bernie Sanders both have more support than Trump, but Trump is getting way more coverage. Here's
an article for Washington Post's The Fix which notes that Trump gets twice the coverage of Clinton in nightly newscasts, and a whopping 23x the coverage of Sanders.
I've also been regularly keeping an eye on
this project on The Atlantic which tracks TV coverage from a broader variety of news outlets. In the last 7 days, Trump has gotten 5.3x the mentions of Clinton, and 20.7x the mentions of Sanders. That's utter insanity and just breeds more insanity.
Anyway, before I go, I'll also point out a couple places for getting averaged information on polling data:
Real Clear Politics and
Huffington Post's Pollster section.
"Surprise" poll results usually aren't really surprises, so those two are really useful to have handy.
