INDIANA -- Ted Cruz dropped out of the presidential race Tuesday night after Donald Trump's victory. "We gave it everything we've got, but the voters chose another path," Cruz told his supporters Tuesday night.
"With a heavy heart, but with boundless optimism for the future of this nation, we are suspending our campaign," He said. "But hear me now, we are not suspending our fight for liberty."
Donald Trump, speaking out after his victory in Indiana, said "What (Ted Cruz) did is really a brave thing to do and a great thing to do."
For his part, Ohio Governor John Kasich insisted he would remain in the race. He tweeted a message to Cruz: "Sen. @TedCruz should be proud of his strong and disciplined campaign. Texas is lucky to have you. Best wishes going forward. -John"
Though the real-estate mogul won't secure the 1,237 delegates he needs to formally claim the nomination until June, his Indiana triumph makes it almost impossible to stop him.
Following his decisive wins in New York and other East Coast states, the Indiana victory could put Trump within 200 delegates of the magic number he needs to clinch the nomination.
Trump's candidacy has galvanized the GOP, bringing in voters -- especially in regions like the Rust Belt -- that might not otherwise be attracted to the party's message. In the process, he's toppled a GOP field that, at the start, included many well-respected governors and senators.
GOP elites now face the long-feared reality of Trump as an outsider nominee who will lead them into the fall campaign after splitting the party, overturning establishment and conservative power bases and alienating key general election voters with incendiary rhetoric.
The anti-Trump movement said it would fight on as Trump was still short of the delegates needed to secure the nomination. Katie Packer, the chair of Our Principles PAC, said there is still time for the Trump to "continue to disqualify himself in the eyes of voters."
"We continue to give voice to the belief of so many Republicans that Trump is not a conservative, does not represent the values of the Republican Party, cannot beat Hillary Clinton, and is simply unfit to be President of the United States," she said in a statement.
"Tonight's results are not going to alter Gov. Kasich's campaign plans," said John Weaver, Kasich's chief strategist. "Our strategy has been and continues to be one that involves winning the nomination at an open convention."
Meanwhile, Bernie Sanders beat national front-runner Hillary Clinton the Indiana Democratic primary; however, he is unlikely to cut deeply into her large delegate lead that has her on track for the nomination.
