DETROIT — With Donald Trump bleeding support from high-profile Republicans, Hillary Clinton’s campaign launched a series of television ads Monday seeking to persuade rank-and-file GOP voters to side with the Democratic nominee in November.

The four ads, airing in battlegrounds states, seek to highlight different concerns about Trump, with testimonials from Republican voters as to why they believe he is unqualified to be president.

The ads feature a former Reagan administration official, a Republican mother of a child with autism, a Republican Army veteran and a former local Republican party official.

Among them is Douglas G. Elmets, a White House spokesman under former president Ronald Reagan, who has been helping recruit Republicans to vote for Clinton for some time. Elmets was among the Republicans who spoke at the Democratic Convention in late July.

Though the push to appeal to Republicans began months ago, Clinton aides see a larger opening in the wake of Trump’s uneven performance in the first presidential debate and the widespread condemnation of lewd comments he makes about women in a 2005 video that surfaced Friday.

The campaign has also launched an overlapping push to court white, working-class male voters, who have been the bedrock of Trump’s support. Clinton is campaigning Monday in Michigan and Ohio, two states where that demographic will factor significantly into the outcome.

Aides said the new 30-second ads are airing as part of a national cable campaign and as part of existing ad campaigns in Florida, Iowa, Nevada, North Carolina, Ohio and Pennsylvania.
