D. Raja, a businessman and Mt. Lebanon commissioner, is poised to enter the Republican race for Allegheny County executive.
Mr. Raja, who could not immediately be reached for comment, has called a variety of senior county Republicans to alert them to his interest.
According to an associate, he plans to make a formal announcement some time next week.
The news of Mr. Raja's plans for the race circulated as Patti Weaver, an architect of the Pittsburgh Tea Party movement, was about to formally launch her bid for the Republican nomination at a rally today at the City-County Building.
"My only comment, is, let the best person win," Ms. Weaver said of the news of Mr. Raja's prospective candidacy.
County Councilmen Matt Drozd and Chuck McCullough have also said that they are considering bids for the GOP nomination, but neither has announced a final decision.
Mr. Raja's decision sets the stage for contested races on both sides of the primary ballot for executive. County Controller Mark Flaherty and county Council President Rich Fitzgerald have announced their candidacies for the Democratic nomination to succeed Dan Onorato, who chose not to run for a third term.
