Republican presidential hopeful Newt Gingrich bade farewell to his 2012 presidential campaign on Tuesday, AFP reported.

Gingrich posted a video on his website in which he said that he plans to make an official announcement regarding the suspension of his campaign the following day.

The former speaker of the House of Representatives said in the video he wanted to “give you an insider advanced notice that on Wednesday I'll be officially suspending the campaign as part of a press event.”

Gingrich added, “We're still faced with a tremendous crisis of our country's future. A re-election of Barack Obama would be a genuine disaster.”

AFP noted that Gingrich did not mention by name his Republican rival Mitt Romney, a former Massachusetts governor and the party's presumptive nominee, but said that “all of us have an obligation, I think, to do everything we can to defeat Barack Obama.”

Last week, Gingrich's spokesman acknowledged the writing was on the wall for the embattled candidate, after Romney swept all five of the state contests that were held on April 24.

In his video, Gingrich thanked his nearly 180,000 campaign donors, thousands of volunteers and the nearly 2.5 million people who voted for him in 43 state contests. He only won two states, Georgia and South Carolina.

Gingrich downsized his campaign after he continuously failed to win any states. As part of the downsizing the campaign laid off one-third of its full-time employees and scaled back campaign appearances.

During his campaign he several times took pro-Israel positions, and in one interview went so far as to describe Palestinian Authority Arabs as “invented people”. The remarks angered the Palestinian Authority.

Gingrich also said he would consider granting clemency for Israeli agent Jonathan Pollard, and vowed that if he is elected, he will move the U.S. Embassy from Tel Aviv to Israel's national capital, the city of Jerusalem. 

Gingrich’s withdrawal leaves only Texas congressman Ron Paul in the race against Romney. Paul has consistently placed fourth in the primary season and has no chance of beating Romney.
