We still have six months to go until November. There will be twists and turns throughout, but the electoral fundamentals favor Hillary.
The built-in Democratic advantage of 242 electoral votes shows no sign of cracking. Sorry Repubs, you're not going to win Pennsylvania or Wisconsin. This leaves Hillary to focus on 28 electoral votes on states that are entirely winnable. In other words, follow the Obama map.
The highlighted portion of the quote is what the GOP has to do to really threaten Hillary. I don't see the GOP winning WI or MI, but PA is not out of the question because of the large swath of PA that is more like Appalachia than WI or MI. Trump has really appealed to folks in Appalachia, and Obama has deeply offended them. Appalachia is coal country, and the Democrats have gone too far down the road of "clean energy" to walk back the Obama record on coal.
