Clinton now has a 90 percent chance of winning the Nov. 8 election and becoming the country’s first woman president, according to political odds-makers.

Polls continue to show Trump now losing nearly every demographic group save for white men and the electoral map tipping toward a Clinton landslide, with new surveys showing that even reliably red states like Georgia and Arizona may be about to turn blue. Even a much improved performance in the second debate, when Trump put Clinton on the defensive, did little to slow Trump’s free-fall.

As his own efforts to psyche out his opponents have fallen flat, Trump himself has shown that he can be easily baited. On Tuesday, President Obama twice told reporters that Trump should “stop whining” about his unfounded claims of a rigged election, a comment that seemed intent on provoking a reaction from the thin-skinned candidate whose first real foray into politics was to question Obama’s U.S. citizenship.

After defying expectations and political gravity for 15 months, Trump’s collapse has happened fast—and it has been both shocking and predictable. Heading into the first debate last month, the race for the White House looked to be close to a toss-up. But Trump delivered an unfocused and at times incoherent performance, exacerbated in the days that followed as he walked into Clinton's trap and continued to fat-shame a Latina former Miss Universe for gaining weight during her reign.
