GOP presidential hopeful Rick Santorum (R-Shouldn’t You Be at Home Taking Care of Your Daughter?) has shrugged off his third-place finish in Florida and gone full-tilt into Nevada for this Saturday’s caucuses, as The Hill duly notes:

Santorum up in Colorado, Nevada with anti-Gingrich commercial

Fresh on the heels of announcing January fundraising numbers in excess of $4 million, Rick Santorum’s presidential campaign announced a new television ad that will begin airing Tuesday in Colorado and Nevada.

The ad attacks Newt Gingrich as being too liberal for the GOP nomination by arguing that he shares many policy positions with President Obama and House Minority Leader Nancy Pelosi (D-Calif.).

Said ad:

As one CNN chin-stroker (the hardworking staff forgets which) noted last night, Santorum could level the same charges at Mitt Romney (R-Have I Won Yet?), but chooses to go after Gingrich instead, in a (probably vain) attempt to turn the Republican presidential primary into a two-man race.

Not gonna work. But Mitt says thanks.
