The flight jacket is back.
Joe Sestak -- former congressman, U.S. Admiral and 2010 Democratic foe of Pat Toomey -- announced today that he will explore another Senate run in 2016 and not governor next year.
He is exploring another run -- he says in the video announcement above -- because "the U.S. Senate's lack of leadership and lack of accountability in not confronting our challenges has meant our country careens from crisis to crisis, paralyzing the governing of our nation."
He amassed a $460K warchest in the first quarter of the year, heightening mystery (including among the GOP) about his next steps. The move also helps clear the giant, developing field of Democrats seeking to face poll-battered Gov. Tom Corbett next year.
Sestak, of Delaware County, lost to Toomey by 2 percentage points in the 2010 GOP wave election and often traveled across Pennsylvania, in his first statewide run, wearing the Navy flight jacket he wears in today's video.
UPDATE from Toomey team spokesman
"Pat Toomey is focused on serving the people of Pennsylvania in the US Senate and hasn't even thought about an election three and a half years from now. He will continue working to build consensus and lead in Washington like he has on job creation, fiscal responsibility, and keeping America safe" Mark Harris, spokesman
