Donald Trump has a double digit lead over Ted Cruz in Arizona heading into Tuesday's Republican primary and is locked in a tight battle with the Texas senator as the favorite among GOP voters in Utah.

Trump now leads Cruz in Arizona 31 to 19 percent. Ohio Gov. John Kasich is tied with Marco Rubio, who has already dropped out of the race, at 10 percent.

Trump Scores Endorsements

Trump is also hoping to ride the recent endorsement of anti-immigration Phoenix sheriff Joe Arpaio to even wider appeal among the border state electorate. The candidate has also bagged the endorsement of former Arizona Gov. Jan Brewer, another immigration hardliner.

Still, given that 30 percent of the state's voters remain undecided and late voters have typically broken against Trump this campaign season, Cruz remains hopeful.

Meanwhile, a recent Utah Policy poll found Cruz leading the field at 18 percent, followed by Rubio at 17 percent and Trump at 13 percent. Meanwhile, 15 percent of all voters said they remain undecided.

The poll also found Cruz scoring exceedingly well among those who describe themselves as "very conservative," earnering 41 percent of that demographic to Rubio's 18 percent and Trump's 15 percent.

Trump, Clinton Widen Leads

On the Democratic side, overall party front-runner Hillary Clinton leads Vermont Sen. Bernie Sanders among democratic voters 51 to 44 percent.  

The picture brightens even more for both Trump and Clinton based on a snapshot of the upcoming New York primary on April 19.

A new Emerson poll shows Trump racing out to 64 percent of the GOP vote, leading Cruz by a staggering 52-point margin. The survey also finds Kasich received absolutely no bounce from his recent home state victory and is stuck at just 1 percent.

Trump also has the highest favorable rating among Republican voters in New York, with 71 percent of voters viewing him favorably against 23 percent who have a negative image of him. By comparison, Cruz's numbers in the state are 52 percent to 44 percent, and Kasich is at 54 percent to 34 percent.

Clinton's lead over Sanders in New York is nearly as big. The former first lady is registering 71 percent of the democratic vote to Sanders' 23 percent, accounting for a 48-point cushion over her liberal challenger.

The former secretary of state leads among some of the most important demographic groups, including Hispanics (85 to 8 percent), African-Americans (72 to 22 percent), women (73 to 20 percent) and men (66 to 29 percent).

As he has throughout much of the election season, Sanders leads among younger voters 53 to 40 percent.

When it comes to potential general election match-ups, the poll shows both Clinton and Sanders besting Trump in the state by an average of 18 points, while Cruz loses to Clinton by an even wider margin of 31 points.  

Among Democrats, the issues considered most important are the economy (29 percent) and race relations (18 percent), while dissatisfaction with government (47 percent) and the state of the economy (29 percent) top the list of Republican concerns.

Hispanics Play Pivotal Role in New York Electorate

A recent Pew Research study found Hispanics now comprise 13 percent of eligible voters in New York, with 1.8 million Latinos eligible to cast their ballots in 2016. Rising numbers of Latinos suggest that the views expressed by each of the front-running candidates on immigration could go a long way in determining who actually owns the state come general election season.

Several media outlets recently reported Latinos across the country are actively seeking to become registered voters in order to cast ballots against Trump in light of his vow to deport 11 million immigrants.

Clinton, on the other hand, has pledged to legislatively tackle immigration reform within her first 100 days in office.
