With Santorum suspending his campaign, Gingrich saw a new hope of reasserting himself as the conservative alternative to Romney. His campaign had been scaling down since his March 24 defeat in the Louisiana primary and was $4.3 million in debt by the end of March. But now it began concentrating on the Delaware primary hoping a win there would be a game changer. The Adelson family that had already supported Gingrich heavily through the "Winning Our Future" super PAC gave another $5 million in late march bringing the PAC's cash on hand up to $5.8 million. But even with all the resources of the Gingrich campaign concentrated in Delaware he still lost the state with 29.4 percent to Romney. On May 2 he officially suspended his campaign. Gingrich won two contest (South Carolina and Georgia) nineteen delegate allocating congressional districts. More than 2.4 million people voted for him and he secured a total of 131 delegates before suspending his campaign. He could only show plurality in two states and was therefore not going to appear on the first ballot nominating the Republican candidate for president at the National Convention. Four states that didn't allocate delegates at their earlier caucuses had conventions in April. At the Wyoming state convention (April 12–14), just after Santorum had suspended his campaign, the state delegates united behind Romney and all 14 at-large delegates pledged to him. The same did not happen the same weekend at Colorado's state and district conventions. Santorum and Paul supporters came together to form the "Conservative Unity Slate" in an attempt to stop all the National Convention delegates from Colorado from supporting Romney. However, Romney won a narrow plurality in the state delegation despite this opposing slate. Missouri had its district conventions a week after (April 21). Santorum had carried every county at the nonbinding primary in February and many of his supporters threw their support to Romney who got half of the delegates. Paul won one out of the eight district conventions. Minnesota's district conventions were spread out over most of April and they were all but one won by Paul who secured a plurality in the state delegation even before the state convention in May. Romney won all eight primaries of the month and on April 25 the RNC declared Romney the presumptive nominee, putting resources behind him. On May 2, 2012, Newt Gingrich "mothballed" his campaign saying that a second term of president Obama would be disastrous. Gingrich mentioned Republican front-runner Mitt Romney during his press speech, but did not endorse him. He intended to officially endorse Mr. Romney at a "to-be-scheduled event" featuring both Republican leaders.
