WASHINGTON -- What's up with the Republican polling roller coaster this year?

On Sunday, Gallup's daily tracking poll on the Republican presidential race showed former Sen. Rick Santorum (R-Pa.) moving ahead of former Massachusetts Gov. Mitt Romney by eight percentage points (36 to 28 percent) nationwide. Santorum has gained 20 points in 12 days.

Thirteen days earlier, on February 7, Romney led with 37 percent in Gallup's tracking poll, followed by former House Speaker Newt Gingrich (21 percent) and Santorum (17 percent).

On January 27, Gingrich led Romney, 32 to 26 percent.

Twelve days before that, on January 15, Romney led Gingrich, 37 to 14 percent.

And that's just the last two months. Gallup reports that the lead switched seven times more in 2011.

Why the volatility? Take a look at our quick take via video, drawing on this earlier Huffington Post report.
