Presidential Race: Time to Ante Up and Pitch In

In a typically thorough and brilliant analysis, Nate Silver's fivethirtyeight.com election prediction operation finds the gap between Hillary Clinton and Donald Trump narrowing. Read his latest ten-point analysis here. Silver has predicted the last two presidential elections with remarkable accuracy. His projections currently give Clinton about a two-to-one 67% to 33% likelihood of winning the election.

I said I'd be concerned and comment if Trump's chances got above 30 and so they have. I am concerned. Clinton's still in the driver's seat in popular vote and electorally, but the slide had better stop. What's happening? She's been off the campaign trail most of August, raising a massive haul of money ($140 million). She needs to and is now back campaigning. That money needs to buy a flood of effective adds, positive and negative, and fund a great organizational registration and get out the vote, (GOTV) effort, especially in the battleground states. This is where Clinton would have a big edge in states that are very close. She has dozens of offices in Florida and Ohio, for example, while Trump has only a small handful. But she's also hurt by the incessant drip about emails, eroding credibility among the persuadable. Clinton must break through the sleaze reporting with her positive growth plans and needs to (and should) turn in her normally impressive debate performances which should highlight how much more she knows, is better prepared, and is personally suited for the presidency than Trump.

The odds are about right. She is ahead and ought to win. But there is enough of a chance for Trump that it's not a certainty. That's cause to keep taking action. I just made my fifth contribution to the campaign since she announced. The Young Democrats college club I sponsor voted today to join the Registration and GOTV effort and commit to signing up 200 voters and then walking precincts the last two weeks up to Nov 8. We're still ahead and have the inside track with a more plausible route to the winning total of 270 electoral votes. But it's no time to rest easy at all.

First 2016 Presidential Vote Forecast is Good News for Clinton

Democrats should take heart at the first comprehensive analysis of the 2016 presidential race by election prognosticator par excellence Nate Silver: Hillary Clinton has about an 80% chance of winning, he says. This is delivered, of course, with the essential warning that it's still very early at four months out, and no one should be counting any chickens yet. Go to his full article here. 

The current model, based on polling alone, has Clinton ahead in the popular vote 48.8% to 42.0% for Donald Trump, with Libertarian candidate Gary Johnson currently at 7.9%. The state map has Clinton with 348 electoral votes to Trump's 190. Battleground states where the lead is relatively close shape up this way. Clinton is ahead in Nevada, Colorado, Iowa, Florida, North Carolina, Virginia, Ohio and New Hampshire. Trump has the edge in Missouri, Arizona and Georgia. The statistical probability of a Clinton election is 79.2%, for a Trump win is 20.7%. You can go to Silver's FiveThirtyEight.com site and play with his election maps here.

Silver's "Polls Plus" model gives Trump a slightly higher chance for an upset. This calculation goes beyond current polls to add in historical data such as the effect of a two-term president of one party not seeking re-election, and the present economic conditions under those circumstances. This calculation gives Clinton a 73.3% chance compared to Trump's 26.6%. The electoral vote probability in this scenario has Clinton at 316 and Trump at 222. The chief switches are to put North Carolina in the Republican column and pull Arizona and Georgia out of near tossups and assign them "lean Republican" status.

Silver's statistical wizardry is legendary. He correctly called the outcomes in 49 of the 50 states for the 2008 election, and forecast all 50 states correctly in 2012.
