Cruz puts dent into Trump's delegate lead; Clinton extends her advantage

Republican presidential candidate Donald Trump greets supporters after speaking at a campaign rally in New Orleans Friday

Nebraska Republicans will vote for the GOP nominee in the state's May 10 primary. Meanwhile, 23 delegates are up for grabs in Puerto Rico.

He attributed his strong showing to conservative coalescing behind his candidacy.

"The scream you hear, the howl that comes from Washington DC right now is utter terror at what we the people are doing together", Cruz said as early results come in.

Cruz, 45, has run as an outsider bent on shaking up the Republican establishment in Washington.

It was a state Donald Trump made a point of saying he did not want to lose. U.S. media reports say he won in the states of Lousiana and Kentucky.

Republicans are battling for 155 delegates in Kansas, Kentucky, Louisiana and ME, while Democrats are going to the polls in Kansas, Louisiana and Nebraska with 109 pledged delegates at stake.

"It's my opportunity to revolt", said Betty Nixon, a 60-year-old Trump voter in Olathe, Kansas.

US Republican presidential candidate Senator Ted Cruz speaks to supporters in Kansas.

Then, addressing reporters, Cruz declared that "it would be a disaster" if Donald Trump won the Republican Party's nomination, and he reiterated that he is the best alternative to Trump. "The establishment is just being left out". Cruz had 231, Rubio 110 and Kasich 25.

Including results from Nebraska, she now has at least 1,076 delegates according to The Associated Press count, compared to 446 for Sanders. Turnout in Republican presidential caucuses in Kansas exceeded the party's most optimistic predictions.

On March 15, the delegate-rich states of Florida, Illinois, Ohio, Missouri and North Carolina will vote.

If Trump takes both Florida and OH he would be almost impossible to stop.

Thousands of voters waited to vote with the line snaking through the large caucus room and outside the hall. After big victories on Super Tuesday, Trump sounded more like he was running in a general election, describing himself as a "unifier" and attacking Democratic candidate Hillary Clinton.

She also said she was thrilled to add to her delegate count and expected to do well in Michigan's primary on Tuesday. The caucuses would determine how the state's 33 other delegates would be allocated, also proportionally.

Sanders had events in OH on Saturday as the Democrats kept close watch on those two big states and their upcoming delegate hauls. He needed to show some momentum, and he claimed it in in the way he has tended, by marveling at his unexpected progress since the start of the campaign.

However, he still faces a narrow path to victory.
