Hillary Clinton and Donald Trump ended Super Tuesday by looking toward the general election and attacking each other.

"And we know we've got work to do. But, that work, that work is not to make America great again," Clinton said, aiming at Trump as she celebrated her multiple wins. "America never stopped being great."

The Democratic front-runner said that instead of talking about how to make America great again, Trump's campaign slogan, we should focus on making America "whole again."

Trump scoffed at Clinton's reworking of his slogan.

"[Hillary's] been there for so long. I mean, if she hasn't straightened it out by now, she's not going to straighten it out in the next four years," he said. "It's just going to become worse and worse. She wants to make America whole again, and I'm trying to figure out what is that all about? Make America great again is going to be much better than making American whole again."

Neither candidate put away their primary opponents in a clean sweep. Texas Sen. Ted Cruz won three states and Florida Sen. Marco Rubio carried one. On the Democratic side, Vermont Sen. Bernie Sanders won four states.

But both Trump and Clinton cemented their front-runner status. Trump won seven of the 11 states voting Tuesday, taking Southern states like Alabama, Georgia and Arkansas while also doing well in New England with victories in Massachusetts and Vermont.

In Vermont, Trump had to beat back a surprisingly strong challenge from Ohio Gov. John Kasich. Rubio also outperformed his poll numbers in Virginia, giving the billionaire a run for his money. But Trump outlasted both opponents.

Clinton maintained her Southern firewall, winning Alabama, Arkansas, Georgia, Tennessee, Texas and Virginia. She also beat Sanders in Massachusetts, a state where he was expected to compete well.

Voters in a dozen states headed to the polls Tuesday to cast ballots for their party's presidential nominee, the first time multiple states have voted simultaneously in 2016.

Super Tuesday came at a pivotal time in both parties' nomination fights, as anti-Trump Republicans are increasingly in revolt against their party's front-runner and Clinton has started to consolidate her lead among Democrats.

Sanders won his home state of Vermont easily, and pulled an upset in Oklahoma. He also took the caucuses in Minnesota and Colorado. Cruz fought back with wins in Texas, his home state, and Oklahoma. Rubio managed to win Minnesota, despite disappointments elsewhere.

Trump entered Super Tuesday leading in most of the 11 states holding Republican primaries or caucuses, often by huge margins. But since last week's GOP presidential debate, he has been locked into a fierce war of words with Rubio, who has dominated media coverage in the past few days but is looking to notch his first win of the cycle. Trump also set off a firestorm when he declined several opportunities to disavow David Duke and the Ku Klux Klan, causing many Republican leaders — including 2012 nominee Mitt Romney — to start speaking out against his candidacy.

By most conventional measures, Trump has a clear path to the Republican presidential nomination. But both the party establishment and the conservative movement have become increasingly vocal in their criticism of Trump and are gaming out scenarios to try to stop him. Rubio has rallied Trump's detractors by calling the billionaire businessman a "con artist."

But Rubio's attempt to define this as a race between Trump and himself was thwarted by Cruz's wins. The Texas senator instead asked the other non-Trump candidates to "prayerfully consider" dropping out of the Republican presidential race.

"Tomorrow morning we have a choice," he said. "So long as the field remains divided, Donald Trump's path to the nomination remains more likely and that would be a disaster for Republicans, for conservatives and for the nation."

Speaking before Rubio won Minnesota, Cruz told his supporters "the candidates who've not yet won a state, who've not racked up significant delegates" ought to contemplate withdrawing for the good of the party. He positioned himself as the conservative alternative to Trump.

Cruz's biggest upset of the night was in Alaska, where Trump had former Gov. Sarah Palin's endorsement. The caucuses gave Cruz the final win of Super Tuesday, as the state was decided Wednesday morning Eastern time.

Rubio now won't be able to push Cruz out of the race. But the Texas senator has at times underperformed with evangelicals and Rubio will remain the choice of Republicans who believe it will take a coalition of the GOP establishment and movement conservatives to best Trump.

Trump was introduced at his post-primary press conference by New Jersey Gov. Chris Christie. Christie stood behind the billionaire as he tore into Clinton, congratulated Cruz on winning Texas and badmouthed Rubio's performance.

Sanders came into Tuesday having lost three of the first four Democratic contests to Clinton, although he did win New Hampshire by better than 20 points. While at a major disadvantage in Southern primaries with a large percentage of black voters, he hoped New England and the caucus states would help him stay in the race.

But as the odds of a Trump-versus-Clinton race grow, the Democrats hope to use the billionaire's controversial comments to turn out women and minorities in November. The turnout they once were able to get from enthusiasm for Barack Obama they now hope they can get from fear of Trump.

Restive Republicans aren't ready to unite behind Trump, despite the front-runner's assurances that "when we unify, there's nobody, nobody, that's going to beat us." Yet it is increasingly clear that Trump has the easiest path to the required 1,237 delegates of any of the candidates still running. He is going to begin demanding the same deference afforded traditional Republican front-runners in the past.

While neither Sanders nor the two senators running for the GOP nomination have reason to give up yet, Clinton and Trump remain firmly in control. They both know it, which is why they have each started thinking about November.
