In case you missed it, polls released this week are giving us a clearer picture of Inland voters’ preferences in the presidential race.

Results from the nonpartisan Field Poll show billionaire businessman Donald Trump leading Texas Sen. Ted Cruz 45 percent to 23 percent among likely voters in “Other Southern California,” which the poll defines as nine counties outside of Los Angeles County. Statewide, Trump leads Cruz 39 percent to 32 percent.

There wasn’t a regional breakdown in the Field Poll for the Democratic presidential nomination. But Vermont Sen. Bernie Sanders has made up a lot of ground on former secretary of state Hillary Clinton, who now leads Sanders among likely voters 47 percent to 41 percent. She led Sanders 73 percent to 10 percent in February 2015.

A SurveyUSA poll of California registered voters conducted in late March and early April found Cruz leading Trump 43 percent to 30 percent in the Inland Empire among Republicans, with Trump holding an 8 percentage point edge over Cruz statewide. The poll had Clinton leading Sanders 65 percent to 27 percent among Democrats in the IE and 53 to 39 percent in California overall.

POLITICS: Trump holds lead over Cruz in California primary

The June 7 primary is looming as potentially crucial in the race for the Republican and Democratic presidential nominations, especially for the GOP candidates. California has 172 GOP delegates up for grabs, and Trump’s performance in the Golden State could determine whether or not he gets the 1,237 delegates needed to win the nomination outright and avoid a brokered Republican National Convention that could result in another nominee.

All but 13 of the Republican delegates are awarded by California’s 53 congressional districts. Win a district and a candidate gets its three delegates, meaning the GOP campaign for California could be waged district-by-district.

Cruz is holding rallies Monday, April 11 in Irvine and San Diego.
