Lansing (Michigan): Donald Trump swept to victory in the Mississippi and Michigan presidential primaries on Tuesday, deepening his grip on the Republican nominating contest. Democrat Hillary Clinton easily carried Mississippi but was locked in a close race with rival Bernie Sanders in Michigan.
The primaries offered Trump and Clinton a chance to pad their leads and start turning toward the general election. But Sanders was hoping to prevent a Clinton coronation with a strong showing in Michigan, the night's biggest prize and the first Midwestern industrial state to vote in the 2016 race.
Trump, reveling in his victories at one of his Florida resorts, spoke like a general election candidate, emphasizing the importance of helping Republican senators and House members get elected in November. But he still took on rival Ted Cruz, who is closest to Trump in the delegate count.
"He's always saying I'm the only one who can beat Donald Trump," the businessman said. "But he never beats me."
Trump entered Tuesday's contests facing a barrage of criticism from rival candidates and outside groups who fear he would deeply damage Republicans' chances of winning in November. While a handful of recent losses to Cruz have raised questions about Trump's durability, Tuesday's contests marked another lost opportunity for rivals to slow his momentum.
Ohio Gov. John Kasich had campaigned furiously in Michigan in recent days. He's yet to win a primary but hoped a good showing in Michigan would give him a boost heading into next week's crucial contest in his home state.
Speaking to a crowd in Lansing, Kasich said a strong showing in Michigan would show the country "that it's a new day in this presidential campaign."
Republicans were also holding contests Tuesday in Hawaii and Idaho. Republican candidates were fighting for 150 delegates, while 179 Democratic delegates were at stake in the party's two primaries. The delegates will select each party's presidential nominee at national conventions in July.
The economy ranked high on the list of concerns for voters heading to the polls in Michigan and Mississippi. At least 8 in 10 voters in each party's primary said they were worried about where the American economy is heading, according to early exit polls conducted for The Associated Press and television networks.
Among Democrats, 8 in 10 voters in both states said the country's economic system benefits the wealthy, not all Americans.
Sanders has sought to tap into that concern, energizing young people and white working-class voters with his calls for breaking up Wall Street banks and making tuition free at public colleges and universities. Michigan, with big college towns and a sizeable population of working-class voters, should be a good fit for him. But Clinton has led in polling.
Sanders' troubles with black voters were evident once again Tuesday. Clinton won nearly 9 in 10 black voters in Mississippi.
Tuesday's contests are a prelude to next week's high-stakes primaries in Florida and Ohio. Like Kasich, Rubio must win his home state in order to remain a viable contender.
Rubio has received endorsements from a steady stream of senators, governors and other high-profile Republican officials. But his backing from voters has lagged, and he entered Tuesday's contests with just a pair of victories in the Minnesota caucuses and Saturday's Puerto Rico primary.
If Rubio and Kasich can't win at home, the Republican primary appears set to become a two-person race between Trump and Cruz. The Texas senator is sticking close to Trump in the delegate count and with six states in his win column, he's arguing he's the only candidate standing between the brash billionaire and the Republican nomination.
During a campaign stop at a North Carolina church Tuesday, Cruz took on Trump for asking rally attendees to raise their hands and pledge their allegiance to him. He said the move strikes him as "profoundly wrong" and is something "kings and queens demand" of their subjects.
"I'm not here asking any of you to pledge your support of me," Cruz said, to thunderous applause and cheers. "I'm pledging my support of you."
Some mainstream Republicans have cast both Trump and Cruz, an uncompromising conservative, as unelectable in a November face-off with the Democratic nominee. But they're quickly running out of options and are increasingly weighing long-shot ideas such as a contested convention or rallying around a yet-to-be-determined third-party candidate.
Heading into Tuesday, Trump led the Republican field with 384 delegates, followed by Cruz with 300, Rubio with 151 and Kasich with 37. Winning the GOP nomination requires 1,237 delegates.
Among Democrats, Clinton had accumulated 1,134 delegates and Sanders 502, including superdelegates, party leaders and elected officials who can vote for the candidate of the choice at the convention. Democrats need 2,383 delegates to win the nomination.
