In a speech in Gettysburg, Pa. on Tuesday, Santorum said that "this presidential race is over for me."

Santorum had recently cancelled several campaign events to care for his three-year-old daughter, who was hospitalized after suffering from complications for a rare genetic disorder.

Santorum was the chief competitor for former Massachusetts Gov. Mitt Romney, the frontrunner in the race for the Republican presidential nomination.

Throughout the campaign, Santorum emerged as a "conservative" alternative to the more moderate Romney and while Santorum did win contests in Iowa, Colorado, Minnesota and Kansas, he could not overcome the insurmountable lead Romney had built with a string of primary wins in the last two months.

Santorum was popular within some circles of the Jewish community and even went as far to state that he would bomb Iran if it refused to dismantle its nuclear program.

"I would be saying to the Iranians, you either open up those facilities, you begin to dismantle them and make them available to inspectors, or we will degrade those facilities through air strikes," Santorum said during a January interview on NBC's "Meet the Press".

While former U.S. House Speaker Newt Gingrich (R-Ga.) and Rep. Ron Paul (R-Texas) remain in the race, the withdrawal of Santorum removes one more hurdle for Romney who is now the presumptive nominee for the Republicans.

Republican Jewish Coalition Executive Director Matthew Brooks told WJW that this was "an important day in the campaign...in terms of solidifying and unifying behind Mitt Romney as the Republican nominee."

In addition, Brooks emphasized that the upcoming race between Romney and President Barack Obama will be "a critically important race for the Jewish community" on matters pertaining to both foreign and domestic policy.
