Pileggi faces a challenger in the primary
Howard, 66, describes himself as a Tea Party Republican. He has a Ph.D. in chemistry and served in the 82nd Airborne Division.
"I am limited government conservative ... who believes in fiscal responsibility," he said.
It's undeniable that it could be a tough battle for Howard. He faces the powerful Pileggi, who has been state senator since 2002.
Pileggi, 53, defeated state Rep. Thaddeus Kirkland, D-159, of Chester, in a special election after the death of Clarence D. Bell. He was nominated majority leader of the Pennsylvania Senate in 2006 and has held the position since.
