— "There was even a time when he didn't get an Emmy for his TV program three years in a row, and he started tweeting that the Emmys were rigged against him,” she said of Trump's claim that the 2016 election is rigged.

Trump, being Trump, offered a quick retort to most of these. “You're the puppet,” he said after the Putin comment. “You can't,” he said when she offered to translate his tax plan. “Should have gotten it,” he said of the Emmy. But he didn't seem to lose his composure, and he didn't lash out.

Until.

In the final five minutes of the debate, all of the poking and prodding finally wore him down, and elicited the response Clinton was looking for. She needled him again, suggesting that he would figure out a way to avoid paying payroll taxes for Social Security — much like his avoidance of federal income taxes.

“Such a nasty woman,” he said.

It took 85 minutes to get there, but Clinton's diligence and subtle sniping had finally created one of probably two signature, unhelpful moments for Trump in the debate (the other: him saying he may not accept the results of the election).

This, of course, isn't a new campaign dynamic. Clinton has telegraphed this strategy since the Democratic National Convention, in which she said Trump was someone who could be easily “baited with a tweet.” And at that convention and ever since, she has successfully baited Trump into all manner of unhelpful decisions and comments — from feuding with a Gold Star family to her invoking former Miss Universe Alicia Machado at the first debate to getting him to admit he has avoided paying federal income taxes.

And each time, it has reinforced Trump's central vulnerability: that he lacks the temperament to be president. A Washington Post-ABC News poll last week showed that 62 percent of people said Trump doesn't meet that standard.

The difference on Wednesday night was that Trump seemed bent on not getting pulled into these kinds of squabbles and making an unwieldy comment the focus of the after-action.
