So, former speaker Dennis Hastert's seat, in one of the redder districts in the country, with his hand-picked succesor as the candidate, is now in the hands of a Democrat - who received a last minute endorsement and commercial from Barack Obama.
In a stunning upset Saturday that could be a sign of trouble for Republicans this fall, a little-known Democratic physicist won the special election for a far west suburban congressional seat long held by former GOP House Speaker Dennis Hastert.
Rookie candidate Bill Foster scored a comfortable victory over Republican dairyman Jim Oberweis, who lost his fourth high-profile contest in six years, after an expensive and highly negative contest.
Foster had 53 percent to Oberweis' 47 percent with all of the unofficial vote counted.
Yes, we can.
