Rick Santorum drop out of the Republican race for the White House

I was really surprise that Rick Santorum drop out of the Republican race for the White House so early, I guest he felt that his chances of getting the number of delegates needed to win the Republican primary wasn't  possible base on the math, therefore the best he could do to preserved his political future is leaving the race with some dignity. I think he did the right for his political future considering how the second running always become the favorite in the next presidential circle.
