NATE SILVER: Why Clinton’s Position Is Worse Than Obama’s.

If Clinton lost New Hampshire but won her other firewall states, each candidate would finish with 269 electoral votes, taking the election to the House of Representatives. Or maybe not — if Clinton also lost the 2nd Congressional District of Maine, where polls show a tight race and where the demographics are unfavorable to her, Trump would win the Electoral College 270-268, probably despite losing the popular vote.

Couldn’t Clinton win Nevada to make up for the loss of New Hampshire? Or Florida? Or North Carolina? Well … of course she could. All those states remain highly competitive. The point, as we’ve said before, is just that Clinton’s so-called firewall is not very robust. If you’re only ahead in exactly enough states to win the Electoral College, and you’d lose if any one of them gets away, that’s less of a firewall and more of a rusting, chain-link fence.

To illustrate this, let’s compare Clinton’s current position in our polls-plus forecast1 — which gives her a 65 percent chance of winning the Electoral College — to FiveThirtyEight’s final election forecast in 2012, which gave President Obama a 91 percent chance. How could the model be so much more confident in Obama’s chances than in Clinton’s, even though we projected he’d win by 2.5 percentage points nationally and she’s ahead by 2.8? Part of it is because there are far more undecided and third-party voters this year, which could lead to a last-minute swing, or a polling error, and makes the model more cautious.

The answer is much simpler than Silver lets on.

Clinton is a terrible campaigner with a terrible record as Secretary of State and with no record as a Senator. She’s only gone as far as she has because of underhanded support from the MSM and the DNC, because the GOP nominated someone with similar weaknesses, and because she inherited the Obama machine’s impressive digital tools.

Take those away and the Democrats would be looking at a Dukakis-size loss on Tuesday.
