The former Major League pitcher, who last played for the Boston Red Sox in 2008, said on the HBO show "Joe Buck Live" on Tuesday night that he will not vie for the late Edward M. Kennedy's seat in the United States Senate.
Schilling, 42, had mentioned on his blog earlier this month that he was entertaining the idea and had outlined his political viewpoints. Schilling was a vocal supporter of Republican Arizona Senator John McCain in last year's Presidential election.
On Tuesday, Schilling said he would sit this one out.
"Regardless of the amount of support and outreach that's been given to me, it just did not make sense," Schilling said.
Schilling will not give up on dispensing his opinions, however.
"I think the country is sick and tired of elected officials beholden to special interests," Schilling added. "I think we're at a time and a place where we're voting for the lesser of two evils instead of the best candidate."
