Hillary Clinton has criticized Donald J. Trump for his recent comments about the parents of a slain soldier, and she has accused him of inciting violence when hebrought up gun rights at a rally on Tuesday. What she has not had many chances to do is to attack her opponent on policy.
On Thursday, Mrs. Clinton will get her chance.
In a speech billed as a discussion of how she “plans to help working families,” and held in the Detroit area where days earlier Mr. Trump presented his economic platform, Mrs. Clinton plans to eviscerate her Republican rival over policies that she said would favor the super wealthy and hurt average Americans.
At a rally in Des Moines on Wednesday afternoon, Mrs. Clinton gave a preview of her remarks. She called Mr. Trump’s tax plan “trickle-down economics” that would dole out “big giveaways for those at the top at the expense of everyone else.”
In a new attack, Mrs. Clinton will call Mr. Trump’s plan to reduce corporate taxes the “Trump loophole” and will accuse him of creating policies that help his business and others like it.
Until his speech on Monday, Mr. Trump’s economic plans had been somewhat murky, but his general vow to bring back American jobs and abandon existing global trade deals has resonated with some Rust Belt voters.
Before her remarks, Mrs. Clinton will tour the Futuramic Tool and Engineering factory. She will most likely reiterate her support for making products in the United States and her promise to strengthen labor unions, critical issues in this hard-hit manufacturing center. “The American labor movement helped create the American middle class,” she said on Wednesday.
Mrs. Clinton has tried to gain ground on jobs and the economy, devoting almost every campaign event since her party’s convention last month in Philadelphia to discussing what she would to do create jobs and lift incomes.
There are signs those efforts are working. A CNN poll last week showed that for the first time Mrs. Clinton led Mr. Trump, 50 to 48 percent, on the issue of who voters trust to handle the economy.
