(CNN) - Pitching legend Curt Schilling has decided not to run for the Massachusetts Senate seat left open by the late Sen. Ted Kennedy.
The former Boston Red Sox ace, an outspoken conservative who campaigned for former Republican presidential candidate John McCain last year, told HBO Tuesday he has ruled out mounting a GOP bid for the coveted seat
"Regardless of the amount of support and outreach that's been given to me, it just did not make sense," Schilling said on HBO's "Joe Buck Live."
Earlier this month Schilling told a Boston radio station he was considering running for the seat, though added the chances were slim. Schilling also said then he had been approached by party leaders - including McCain - who advised he should consider mounting a campaign.
But questions arose whether Schilling, a registered independent, would have been allowed to run on the GOP ticket. A recent poll of Massachusetts voters also suggested the former Red Sox star might not fair well in a state-wide political race, garnering less than a 30 percent approval rating.
Republican State Sen. Scott Brown has announced he will run for the seat on the Republican side while state attorney Gen. Martha Coakley, Celtics co-owner Stephen Pagliuca, and Rep. Mike Capuano are battling for the Democratic nomination. Primaries are set to be held on December 8 while the general election will take place on January 19.
