Speaking at Trump’s Convention: Former Democrats, a Rancher and Trump Employees

The Republican National Convention will feature more than two dozen “everyday Americans” as speakers who will help hammer home former President Donald J. Trump’s campaign themes and policies, including four people who previously backed Democrats, according to convention and campaign officials.

All four are from key constituencies that the Trump campaign is eager to win over from Democrats in November as Mr. Trump tries to reverse his election defeat in 2020 by chipping away at the coalition that elected President Biden, including Black voters, Hispanic Americans and blue-collar workers.

The Trump campaign and the Republican National Committee have yet to fully announce a speakers list for the convention, which starts on Monday in Milwaukee. The testimonials from “everyday Americans” are expected to be peppered in between elected officials and candidates, party officials and Mr. Trump’s family members, though the convention has not provided a schedule for when any of its invited guests will speak.

On the list announced Friday is Linda Fornos, an immigrant from Nicaragua who attended Mr. Trump’s rally last month in Las Vegas, where she said she had been repeatedly disappointed by Democrats she had supported previously, including Mr. Biden. The Trump campaign has made winning over Latino voters a priority this year, particularly in battleground states like Arizona and Nevada with sizable Hispanic populations.

Also on the list is Robert Bartels Jr., known as Bobby, an official in a New York union who attended Mr. Trump’s visit with construction workers during the former president’s trial in Manhattan and said he was a “lifelong Democrat.” Mr. Trump has pressed for the votes of blue-collar union workers since 2016 and has sought to divide them from union leaders who often support Democrats.

Annette Albright, a Black woman and a former school employee who convention officials said was a “lifelong Democrat,” spoke earlier this year at a town hall in North Carolina hosted by the political organization Moms for Liberty.
