CHICAGO (AP) -- Democrat Bill Foster knows he doesn't have much time to savor his victory.
Foster snagging former Republican House Speaker Dennis Hastert's congressional seat in a special election this weekend.
The win to fill the remainder of Hastert's term until next January will be a fleeting one for Democrats unless he can hold on to the seat in the fall election for a new, full term.
Foster tells The Associated Press today that the best way to establish a long-term career in Congress is to do a good job from Day One.
The millionaire physicist and businessman defeated wealthy Republican Jim Oberweis after a contentious campaign. He earned 53 percent of the nearly 100,000 votes cast in yesterday's special election.
