WASHINGTON — It would take almost 14 days of eyes glued to the television to watch all the feel-good Hillary Clinton ads that have aired since the general election campaign began last month.

Meanwhile, anyone flipping through the channels looking for positive ads about Donald Trump would be disappointed: He hasn’t yet put up a spot appealing to November voters, and groups supporting him have been similarly silent.

The lopsided commercial airwaves show the presidential candidates have drastically different views of the importance of traditional political campaigning. Trump says he sees little need for advertising at this stage. Instead, he has been banking on media coverage propelled by his celebrity appeal.

As a consequence, Trump has largely ceded control over what the voting public is hearing about him. Clinton’s large batch of biographical ads has given her an opportunity to directly influence views about her image.

Up next is what amounts to an hourlong infomercial Thursday night in Cleveland, as Trump accepts his party’s nomination during a speech that will be televised widely in prime time. Clinton has the same perk the following week from the Democratic convention in Philadelphia.

After that, Trump’s campaign has said he may begin advertising. That would be a dramatic change.

While Trump has aired zero ads, Clinton has been piping thousands of commercials into the homes of swing-state voters in places like Florida, Ohio, North Carolina and Virginia. Specific Florida markets such as Orlando, Tampa and Fort Myers have been favored targets, as well as Denver, for Clinton’s ads.

Since June 8, the day after she became the presumptive Democratic nominee, Clinton has put at least 30,700 commercials on broadcast TV, an Associated Press review of Kantar Media’s campaign advertising data shows.

The majority highlight her work as first lady to expand health care for children.

The few ads paid for by Trump supporters bash Clinton rather than make the case for him. For example, a National Rifle Association ad urges people to vote for Trump by flashing his name for four seconds at the end of a 30-second spot. But the narrator says nothing about him — and doesn’t even utter his name.

Advertising strategists are torn over whether the lack of positive Trump ads matters.
