INDIANAPOLIS -- Sen. Hillary Rodham Clinton, who has been logging 14- and 16-hour days in the run-up to today's balloting in Indiana and North Carolina, this morning stopped by Indianapolis Motor Speedway, where the Indianapolis 500 takes place later this month.

Sunday, she earned the endorsement of Sarah Fisher, the first woman to earn a pole position at an IndyCar Series event, and who is now preparing for the fabled race.

And today, Fisher, an Indianapolis native, showed Clinton -- and a trailing pack of reporters -- around her garage at the speedway as cars roared around the track at more than 200 mph.

Clinton admired Fisher's high-tech race car, -- "That is so neat," Clinton said -- before posing for photos with Fisher and her team, the first owned by a female driver.

"Making history is what it's all about," Clinton quipped.

The New York senator declined to make any predictions about today's results or the race for the Democratic nomination, noting that would be like predicting the winner of the Indianapolis 500 before the race began.

"Every race is filled with the unexpected," Clinton told reporters, piling on one race metaphor after another. "It's like life. ... Life is unpredictable. Racing is unpredictable. Politics is unpredictable."

Clinton accepted a helmet from Fisher before heading off to chat with others working in the infield of the sprawling speedway.

Clinton is scheduled to appear in Indianapolis this evening after the polls close.
