As a senator from Illinois, Obama has been able to raise tremendous amounts of money here.
But Clinton is not giving up on the state. She grew up in Illinois and has many long-time supporters here.
Clinton has been planning a major fundraising event for weeks. Obama just recently added a smaller fundraiser to his schedule. Both will take place this evening.
Flossmoor businesswoman Bea Tayui likes Obama and donated to his Senate race. But she supports Clinton for president.
