Arlen Specter spent more than $12.7 million in his losing Democratic primary effort against Joe Sestak, who spent $6 million, their latest Federal Election Commission reports show.

Specter spent $3.6 million in the last weeks of the campaign -- according his report on April 29 through June 30 fundraising -- and still has $2.7 million in the bank. His total receipts during the primary run (counting giving from individuals and PACs) was nearly $15.7 million -- a big number, but still short of the $18 million Ed Rendell raised in 2002 for his gubernatorial primary against Bob Casey.

Two weeks before the May 18 primary Specter's camp had $5.84 million on-hand. It spent $2.3 million on advertising and $200,000 in direct mail.

After the primary the Specter team began issuing a total of $73,600 in refunds to PACs and other contributors, including prominent Pittsburghers Elsie and Henry Hillman, and Penguins co-owner Ron Burkle.

Sestak had $2 million in cash on hand at the end of the 2nd quarter reporting period, to the $4.65 million held by Republican opponent Pat Toomey.

While some of the Sestak camp's $5.98 million in spending came after the May 18 primary matchup, most was before -- most significantly though $2.9 million in television advertising through the Campaign Group.
