Santorum funds rise after shock victories

Republican presidential contender Rick Santorum claimed the momentum a day after his shocking sweep of nominating contests in Colorado, Minnesota and Missouri that dealt a blow to front-runner Mitt Romney.

Even though Romney holds strong advantages in financing and organisation, his campaign will have to refocus to fight the challenge from Santorum, a former US senator from Pennsylvania known for his socially conservative views.

“We definitely are the campaign with the momentum, the enthusiasm on the ground,” Santorum said.
