Huffington Post, Michael Moore give the most incisive (and hilarious) analysis I've seen. We have to understand why this is happening if we are to have a hope of preventing it.
1. Midwest Math, or Welcome to Our Rust Belt Brexit. I believe Trump is going to focus much of his attention on the four blue states in the rustbelt of the upper Great Lakes - Michigan, Ohio, Pennsylvania and Wisconsin. Four traditionally Democratic states - but each of them have elected a Republican governor since 2010 (only Pennsylvania has now finally elected a Democrat). In the Michigan primary in March, more Michiganders came out to vote for the Republicans (1.32 million) that the Democrats (1.19 million). Trump is ahead of Hillary in the latest polls in Pennsylvania and tied with her in Ohio. Tied? How can the race be this close after everything Trump has said and done? Well maybe it’s because he’s said (correctly) that the Clintons’ support of NAFTA helped to destroy the industrial states of the Upper Midwest. ...
And this is where the math comes in. In 2012, Mitt Romney lost by 64 electoral votes. Add up the electoral votes cast by Michigan, Ohio, Pennsylvania and Wisconsin. It’s 64. All Trump needs to do to win is to carry, as he’s expected to do, the swath of traditional red states from Idaho to Georgia (states that’ll never vote for Hillary Clinton), and then he just needs these four rust belt states. He doesn’t need Florida. He doesn’t need Colorado or Virginia. Just Michigan, Ohio, Pennsylvania and Wisconsin. And that will put him over the top. This is how it will happen in November.
4. The Depressed Sanders Vote. Stop fretting about Bernie’s supporters not voting for Clinton - we’re voting for Clinton! The polls already show that more Sanders voters will vote for Hillary this year than the number of Hillary primary voters in ‘08 who then voted for Obama. This is not the problem. The fire alarm that should be going off is that while the average Bernie backer will drag him/herself to the polls that day to somewhat reluctantly vote for Hillary, it will be what’s called a “depressed vote” - meaning the voter doesn’t bring five people to vote with her. He doesn’t volunteer 10 hours in the month leading up to the election. She never talks in an excited voice when asked why she’s voting for Hillary. A depressed voter. Because, when you’re young, you have zero tolerance for phonies and BS. Returning to the Clinton/Bush era for them is like suddenly having to pay for music, or using MySpace or carrying around one of those big-ass portable phones. They’re not going to vote for Trump; some will vote third party, but many will just stay home. Hillary Clinton is going to have to do something to give them a reason to support her — and picking a moderate, bland-o, middle of the road old white guy as her running mate is not the kind of edgy move that tells millenials that their vote is important to Hillary. Having two women on the ticket - that was an exciting idea. But then Hillary got scared and has decided to play it safe. This is just one example of how she is killing the youth vote.
