LOS ANGELES (AP) — Republican presidential candidate Newt Gingrich is drastically reorganizing his money- and delegate-deprived campaign to focus on low-cost social media and an effort to cajole delegates to back him over front-runner Mitt Romney.

Gingrich spokesman R.C. Hammond says one-third of Gingrich’s campaign staff has been laid off and his campaign manager has been asked to resign.

Hammond said Tuesday night that Gingrich’s new strategy hinges on preventing Romney from winning the 1,144 delegates he needs for the nomination. Gingrich plans to spend much less time in primary states and will instead personally call delegates to try to persuade them to back him at the Republican National Convention in August.

Gingrich plans to shift the campaign’s focus to digital outreach — in particular YouTube, Twitter and other social media.
