George W.
Woodward was the regular nominee of the Democratic party for the place.

But Cameron bolted, and with the aid of Whig votes was chosen senator.

He resisted the passage of the tariff of 1846, stood firmly and consistently for the industrial interests of his State, cultivated an alliance with the Whigs in the Senate, and by their aid thwarted all the attempts of the Polk administration to interfere with his plans and purposes in Pennsylvania.

The President endeavored to heal Judge Woodward's wounds by placing him on the bench of the Supreme Court as the successor of the eminent Henry Baldwin.

Cameron induced the Whigs to reject him, and then forced the administration to nominate Robert C.Grier whose appointment was personally acceptable and agreeable to him.
