Iowa Patch Poll: Should Santorum Concede?

The very fact that the 2012 race for the Republican presidential nominee has always been between Mitt Romney and a revolving door of not-Romneys shows the power behind the former Massachusetts governor's campaign.

Rick Santorum is the foremost not-Romney, and we get to claim some credit for that. It was the Iowa Caucus that gave his nearly dead campaign a vital boost of power that he still seems to be riding.

But, has the former Pennsylvania senator taken the post-Iowa Caucus momentum as far as it will go?

It's true that many stories are touting Santorum's Saturday Louisiana primary victory as proof that the race is still on, but the state only added 10 delegates to his total.

Other stories point out that Santorum's victory will come from the South, but there's actually not many delegates left there. The only southern states that have not yet had primaries are Arkansas, North Carolina, Kentucky and Texas.

At this point in the race, Santorum has 273 delegates in tow, but he needs 871 more to win the nomination.

The problem: there are a total of 1,258 left, meaning he'll have to get 70 percent of the remaining delegates to win, which isn't likely when you consider Romney's lead.

Still, he's showing no signs of slowing down, at least in his rhetoric. He claimed Sunday that "bad math" is what makes Romney's chances better.

But is he fooling himself?

Since it's Iowans like us that catapulted Santorum into the thick of the race, we ask you: Is it time for Santorum to step aside and concede that Romney is inevitable?
