Obama & Romney Search for Edge In Final Campaigning Days

PORTSMOUTH, N.H. (AP) — Three days. Nine states — give or take. A magic 270 electoral votes. For President Barack Obama and rival Mitt Romney, the final touch-and-go stretch of campaigning is down to the numbers.

New hiring reports or a new jobless rate. Spending totals or early vote totals. Percentage points and rhetorical points. Frequency of stops or size of crowds.

In a game of metrics, each camp is looking for that last measure that will separate them at the finish line.

Obama's team is planning a series of larger-than-usual events this weekend aimed at drawing big crowds in battleground states including Ohio, Wisconsin and Virginia.

Romney is set to attend a Saturday morning rally in New Hampshire before making an afternoon appearance in Iowa, and two more appearances in Colorado that evening.
