It’s back.

That famous (well, famous in Virginia political circles) TV ad aired by Democratic Sen. Chuck Colgan in 2007 of him imitating Rocky Balboa.

Yes, it even had Rocky music and that run up the steps.

Colgan — now 85 — has filmed a new version of the oldie but goodie.

The longest serving member of the Virginia Senate finds himself in a surprisingly tough race in his Prince William County district against Republican Tom Gordy next month.

Colgan, chairman of the powerful Senate Finance Committee, had said last year that he would probably retire. But this year he said he would run for his 10th term after lobbying by Democrats who hope to keep their slim majority on the state Senate.
