US Republican presidential candidate and Ohio governor John Kasich is dropping out of the 2016 presidential race, according to a senior campaign adviser.
The move by Kasich comes one day after Senator Ted Cruz’s exit made Donald Trump the presumptive GOP presidential nominee.
Kasich, who was mathematically eliminated from the race weeks ago, was planning to make the announcement on Wednesday, campaign sources told the media.
The news comes after the candidate’s weak showing in the Indiana primary contest, where Trump secured a landslide victory and forced Cruz to end his campaign.
Throughout the primary season, Kasich only managed to win one contest — his home state of Ohio — and also lagged in the delegate race, where he failed to overtake Florida Senator Marco Rubio, who dropped out in mid-March.
He only managed to win 154 delegates, compared to Rubio's 172.
In late April, Cruz and Kasich joined forces to knock rival Trump out of the lead in the party’s presidential primaries.
They sought to block the real-estate mogul from gaining the 1,237 delegates necessary to claim the GOP nomination so that they can have a chance to earn the nomination at a contested convention.
But all those plans collapsed on Tuesday, after Trump won more than 60 percent of the votes and won all of the 57 available delegates, raising his total delegates to 1,047, according to an AP count.
On the Democratic side, US Senator Bernie Sanders triumphed over rival Hillary Clinton in Indiana's crucial Democratic primary.
Sanders’ victory on Tuesday boosted the self-declared socialist’s argument that the party’s superdelegates should support him in July’s Democratic convention.
He said he would make history in America through upsetting Clinton’s campaign and defeating Trump in the November general election.
