THE MESSAGE: The ad makes the case that Mrs. Clinton has spent her career preparing for this moment while Mr. Trump has spent his enriching himself and is unfit to be president, because of both to his past record and his recent statements.

THE TAKEAWAY: The tone of the ad is more negative than in those candidates generally produce in the campaign’s closing days, but it is softened somewhat by having Mr. Freeman, and not Mrs. Clinton, deliver the attacks. It also seeks to reinforce what the Clinton campaign has been trying to convey as it courts both Democrats and Republicans— that Mr. Trump’s campaign is all about himself and for his own ego, while Mrs. Clinton’s is about children and the future.

Microtargeting Trump

The Trump campaign has yet to run a Spanish-language advertisement, but in sensing a new pocket of support among Indian-Americans, the candidate himself speaks Hindi, or at least tries to, in a new ad targeting them. “Ab ki Baar Trump Sarkar,” Mr. Trump says, although the “Sarkar” seems to be taken from another take. The ad is tracked by what sounds like traditional Indian music, but features so many clichés and shoddy graphics that many Indian-Americans initially took to social media wondering if it was a spoof.

Greatest Hits

Priorities USA calls it “Trump’s Symphony,” but what follows is probably music to the ears only of Democratic political operatives and supporters. Over the course of 30 seconds, the primary “super PAC” supporting Mrs. Clinton seeks to cram in every caustic comment and controversial policy from Mr. Trump’s 17 months as a presidential candidate into one ad. From calling Mexicans “rapists” to his sexually aggressive comments, the ad closes with big white text on a black background: “We can end this.”

Daisy Style

A new super PAC, formed by former Democratic Senator Bill Bradley and called the 52nd Street Fund, exploded onto the airwaves in Ohio, with an ad that opens with a split-second view of a mountainscape, before a flash and mushroom cloud eviscerate the vista as a narrator notes that a nuclear explosion “could kill a million people.” A news clip follows, of Mr. Trump being questioned about the use of nuclear weapons. The ad has the feel of the famed “Daisy” ad from 1964, which warned of the consequences of a Barry Goldwater presidency. That was intentional: The group announced during the week that its name was derived from a poem about World War II that President Lyndon Johnson read during the famed “Daisy” ad from 1964.
