Harris and Trump will face off in their first -- and maybe only -- presidential debate. Follow live updates. - The Boston Globe

Contributing sentiments towards policy:

44% : I'm betting on a sharp question from moderators to Trump in this vein, given his calls over the weekend to prosecute and jail perceived political foes.
34% : Tal Kopan, deputy D.C. bureau chief: Trump has made a name for himself through disparaging nicknames and belittling tactics when onstage with opponents, but has struggled to settle on an attack line for Harris.
31% : Trump has struggled mightily to figure out how to take credit for appointing the Supreme Court justices that led to the overturning of the federal guarantee of abortion rights in 2022 without alienating voters, particularly women, who are upset by the ruling.
30% : I wouldn't be surprised if Harris also is going in hoping to get Trump on unsteady footing, perhaps by goading him into an unseemly split screen to her calm, prosecutorial persona.
25% : While Trump attacks her as too liberal, Harris has evolved somewhat from the more progressive candidate who ran for president in 2020; in just the last week, she has announced a new tax break plan for small businesses and rolled out an endorsement from Liz Cheney.
24% : It's an issue at the center of the Harris campaign and one in which she has the opportunity to put Trump on the defensive.
22% : Regarding Trump, Biden's performance was so bad that it overshadowed that Trump's last debate was also pretty weak.
22% : Jim Puzzanghera, reporter in the D.C. bureau: I want to see how Trump tries to explain his position on abortion, an issue that has tied him into knots throughout the campaign.
19% : The debate gives her a chance to reach GOP voters turned off by Trump and convince them she is no radical.
12% : Sam Brodey, national political reporter: Democrats grimaced during the first debate as Joe Biden failed to go on offense against Trump, so I'm watching for how aggressively Harris will respond to Trump's inevitable provocations -- particularly if he defends his actions on Jan. 6, or the Capitol rioters, the way he did in June.
