WASHINGTON (AP) -- President Barack Obama and Republican Mitt Romney are launching a 10-day sprint to the finish line in a contest increasingly about momentum vs. math.
Both campaigns are also keeping an eye on the weather. A huge storm barreling toward the East Coast -- and some battleground states -- has both campaigns adjusting their travel schedules and canceling events.
Even at this critical juncture of the campaign, neither side wants to risk the appearance of putting politics ahead of public safety.
The president is pressing on with a campaign trip Saturday to New Hampshire, while Romney is blitzing through Florida.
Romney and Vice President Joe Biden canceled weekend rallies in coastal Virginia.
