MARYLAND MATTERS — After months on the fringes of the Democratic primary for U.S. Senate, running an exploratory campaign, Anne Arundel County businessperson Juan Dominguez plans to become a full-blown candidate on Wednesday.

Dominguez will announce his candidacy at an early evening gathering at the American Legion Post 175 in Severna Park, offering supporters “fun, food and entertainment,” according to an invitation for the event.

In an interview Tuesday, Dominguez said that after a 3 1/2-month exploratory effort, he’s more convinced than ever that he can be a viable candidate in the May 14 primary — and he has developed a populist economic message to press his case.

“What we heard loud and clear from voters, from the middle class, from the working class and from the poor, is that the transfer of wealth to the top 1% over the last 50 years is really unacceptable,” he said.
