Barack Obama doesn't appear to be banking on a big day in Pennsylvania.
The Illinois senator predicted Monday on Pittsburgh radio station KDKA that Hillary Rodham Clinton will get the win she needs in Tuesday's primary, but says he's going to do a lot better than people think.
Clinton's camp says it would be grateful for a single-digit win, as polls have show her consistently ahead of Obama. Clinton began the race with a hefty 20-point lead in several polls in the state, but Obama's extensive campaigning and heavy ad presence have significantly cut into Clinton's lead.
The two candidates have packed their schedules today with events in efforts to drum up last-minute support.
A loss will certainly increase pressure on her to exit the race, with Obama leading in delegates and the popular vote.
Pennsylvania is the largest of the 10 contests remaining, with 158 delegates up for grabs in the primary.
