(CNN)John Kasich dropped out of the Republican presidential race.
Kasich's decision came after he improbably became the last challenger to Donald Trump, who emerged as the presumptive GOP nominee Tuesday night when Ted Cruz dropped out.
Even before winning his home state of Ohio in March, Kasich was facing pressure to get out of the race, with no clear path to victory. His campaign never became more than a spoiler run, designed to keep Trump from getting the 1,237 delegates needed to win the nomination before a contested convention.
Kasich was a somewhat offbeat Republican contender, who laughed at himself on the trail, occasionally took positions more in line with Democrats (like expanding Medicaid in Ohio) and touted his ability to work across the aisle. He sometimes even joked that he would have done better in the Democratic primaries than in the crowded Republican field.
The two-term governor attempted to distinguish himself from the the raucous GOP field by avoiding direct attacks and striking a more positive tone. (His affiliated super PAC, however, was not shy about criticizing opponents for being negative.)
Kasich hugged one supporter at a Georgia town hall who shared a deeply personal story of losing his friend to suicide and comforted another woman at a Virginia town hall as she spoke of her son's autism. And Kasich, himself, shared the deeply personal story of how he found God after losing both his parents in a car crash.
Kasich's decision to suspend his presidential bid does not necessarily mean he won't be on the Republican ticket --- he has been floated as a possible pick for vice president, based in part on his popularity in Ohio, a crucial swing state.
Even after finishing third to Trump and Cruz in Indiana on Tuesday night, Kasich's campaign insisted he would stick around. He had fundraisers scheduled in the Washington area on Wednesday, but canceled them and remained in Columbus for his late afternoon speech.
"Sen. Ted Cruz just dropped out of the presidential race and it's up to us to stop Trump and unify our party in time to defeat Hillary Clinton," Kasich campaign manager Ben Hansen said in a fundraising email to supporters Tuesday night.
Kasich, who served 18 years in the House before a lucrative stint at Lehman Brothers, was long viewed as a 2016 dark horse, running in the crowded "establishment lane" with candidates such as Jeb Bush and Marco Rubio.
He pinned his hopes early on New Hampshire and dedicated the vast majority of his time and resources there. Kasich did well there, finishing second after attending 190 events in the Granite State, according to the NECN
His Granite State focus helped him win the support of key New Hampshire figures including former Sen. John E. Sununu, son of former New Hampshire Gov. John H. Sununu and veteran New Hampshire Republican leader Tom Rath, who was instrumental in Mitt Romney's 2012 bid. He also won endorsements from The New York Times, The Boston Globe, The Nashua Telegraph and other New Hampshire papers.
Throughout the race Kasich played up his fiscal bona fides as the last House Budget Committee chairman to craft a balanced federal budget, during the Clinton administration.
He also talked extensively about his working-class upbringing in McKees Rocks, Pennsylvania, just outside Pittsburgh. He often told the story of when, as a freshman at Ohio State University in 1970, he wrote a letter seeking a private audience with President Richard Nixon.
And his punchline to his Nixon visit? The White House granted him five minutes with Nixon, but he refused to settle for that and took 20 minutes.
On the trail, Kasich occasionally stumbled with voters, delivering blunt answers that were not always popular. In September, he told supporters at a California golf club that "you leave a little tip" for Hispanic maids, drawing criticism from some Latino groups.
And a few weeks after that comment, he told one voter that she would have to "get over" proposed cuts to Social Security.
He earned a spot on the main stage at the first Republican debate last August, riding a bump from his late-July announcement and staying off the undercard stage for each debate afterward. But Ohio ended up being his only moment of triumph.
