This weekend's "Sunday Square Off" brings you our preview of Tuesday's primary elections:

-The likely winners in the major races on the ballot, for U.S. Senate and Arizona governor, and how the general election is shaping up.

-President Donald Trump's potential impact on the primary and general elections.

-The potential upsets in two statewide Republican primaries and a bitter battle in a Democratic primary in a congressional swing district.

Our primary insiders - The Arizona Republic's Laurie Roberts and political analyst Chris Herstam - also discuss why three controversial ballot initiatives, are hung up in court days before the deadline to print the November ballot.

With voter turnout in the Arizona primary breaking records, two experts on voter data tell us who's turning out, what matters to those voters and which party gets the biggest bump.

I'm joined by Josh Zaragoza, a Democratic consultant and digital strategist at Elected Digital, and Republican George Khalaf, pollster at Phoenix-based Data Orbital.

"Sunday Square Off" airs at 8 a.m. Sundays, after NBC's "Meet the Press" with Chuck Todd.
