(CNN) - Rick Santorum's very modest Republican presidential campaign is growing in size.
A top adviser to the former senator from Pennsylvania says the campaign's infrastructure, which has been on a shoestring budget, is increasing.

"Slowly but surely we're adding staff," Santorum senior adviser John Brabender tells CNN. "But we'll do it efficiently. We'll stay nimble."
He says the campaign is now up to speed with their grassroots team and their digital team and that they've now got a volunteer director on staff. But he says it's nothing in comparison to the size of former Massachusetts Gov. Mitt Romney's campaign staff, and Brabender adds that "we're not creating a huge bureaucracy."
Santorum won all three of Tuesday's contests, and the sweep of caucuses in Colorado and Minnesota and a non-binding primary in Missouri is helping his campaign's bottom line.
"We're doing very, very well raising money," Santorum said Wednesday morning on CNN's "Starting Point with Soledad O'Brien." "I think last night we raised a quarter of a million dollars online. So we're doing really well and we feel like going forward we're going to have the money we need to make the case we want to make."
Brabender tells CNN that that quarter million dollars all came after midnight, and he expects the figure to rise throughout the day. Brabender will be a guest on Wednesday at 6pm ET on CNN's "John King, USA."

The Romney Money Machine is going to have Santorun in their sites now, Poor guy!
It doesn't matter how much staff you have Pretty Ricky. It's all about the message. And frankly, yours is based on ideology. The last thing we need in the White House is an ideologue who wants to turn America into a theocracy. He'd rather have the title "Surpreme Leader Santorum."

Rick is a con artist, The reason why he lost his Senate seat in PA, because we did not trust him and he was an unaffected Senator

The amazing phenonmenon of Santorum's success in 4 caucuses is that he went to a state university, he is from immigrant parents, he has no money and no support from the Republican establishements and is essentially from the blue collar mentality and from the streets and not an elitist. Maybe he understands the condition of the hard working middle class. And is not embarrassed about the Judaeo-Christian and western civilization history that created this democrazy. He is starting to appeal to many. If anything he is too honest a little naive that he can appeal to many who have abandoned these values. Jane Arciero
It is still Paul who is the only one capable to heal this country. And don't believe the media, no matter if its about him, Romney, Santorum or Gingrich. LOOK AT THEIR PLANS and ON THEIR RECORD!
Devote some time for America and do your research.

Romney is crazy and Santorum is crazier!
Rick Santorum is not my candidate but he did a good job beating Romney in Colorado
Republicans know exactly what they want. They just have trouble showing it.

Republicans have made it clear as to exactly what is that they want. They dropped the poker faces on Nov 8., 2008. They've been saying it ever since. They want Pres. Obama to fail.
Team Santorium: A losing team.
All Rick's baggage will come out now. Why do we keep sending the people helped create this mess we are in back to Washington? They are like recycled football coaches.
.......and the GOP nominee is...."Newt Gingrich" he is as solid as a rock...and washington needs an insider who knows what is broken and in need of fixing...!
Rick Santorum is a religious fanatic and I could not be happier that he won last night.
R. Santorum has been able to do two things VERY effectively. 1) he presented Gingrich as an erratic and unpredictable candidate. Result: Newt lost the next debate by trying to portray himself as calm; and 2) he placed Willard against the ropes (something no other candidate has been able to do) about his MA health care plan. Result: Willard was clearly frustrated and unable to spin his way out of that debate providing a good knockout punch for future debates. Not a bad performance in my view.
