The Latino vote isn’t a done deal for Democrats, as proven by the Harris-Sanchez contest in California.

Three out of four Latinos say they are not voting for Donald Trump. But Latino elected officials were not exactly thrilled by the Democratic National Convention.

With GOP nominee Donald Trump calling for deportation of all undocumented immigrants, seeking to build a wall on the border and defaming Mexican immigrants as “rapists,” Democrats are expecting record Latino support.

But at the Philadelphia convention, the party’s Latino leaders spoke privately of wanting more attention from the Clinton campaign and the Obama White House.

A prime example of the Democrats’ strained relationship with Latinos is on view in the U.S. Senate race in California. Two Democrats – one Latina and one black – are facing off to succeed retiring Democratic Sen. Barbara Boxer.

Under state law, the top two vote-getters during the primaries advance to the general election, even if they’re both Democrats.

Rep. Loretta Sanchez trails California Attorney General Kamala Harris in the polls and in fundraising. Harris has more than twice as much money on hand as Sanchez, $2.9 million to $1.1 million. If Harris wins, she will be the second black woman ever elected to the U.S. Senate. Sanchez would be the first Latina. (Harris is the daughter of two first-generation immigrants, an Indian-American mother and a Jamaican-American father.)

Sanchez is charging that Harris is the choice of “the party establishment.” Vice President Joe Biden and California Gov. Jerry Brown have endorsed Harris, as has President Obama.

On the Obama endorsement, Sanchez told Univision, “I think they have a friendship of many years. She is African American, as is he. They know each other through meetings.”

Harris fired back that Sanchez “should apologize to the president of the United States.” White House Press Secretary Josh Earnest said the president didn’t know what Sanchez “intended to imply.”

“The president’s endorsement, though, I think spoke volumes about his deep appreciation for Attorney General Harris’ service and her skill,” Earnest said.

But Sanchez got support from fellow Latino politicians.

“Congresswoman Sanchez has served her party and her state in an exemplary fashion for over 20 years,” said Rep. Filemon Vela, D-Texas, earlier this year, when it was clear California Democrats were lining up behind Harris. “Not one single Democratic Latina has ever been in the U.S. Senate, and the California Democratic Party’s position is a disrespectful example of wayward institutional leadership which on the one hand ‘wants our vote’ but on the other hand wants to ‘spit us out,’” Vela fumed.

Then there was Latino disappointment over Clinton’s selection of a white man, Sen. Tim Kaine, D-Virginia, as her running mate. Clinton passed over a number of popular Latino Democratic politicians: Labor Secretary Tom Perez; Housing and Urban Development Secretary Julian Castro; Rep. Xavier Becerra, D-Sacramento; and former Los Angeles Mayor Antonio Villaraigosa.

While the Democrats have made history with the first black president, and now the first woman nominee of a major party, a Latino has yet to appear on the presidential ticket.

“There’s no question that the future of the Democratic Party of America lies with Hispanics,” says Gilberto Hinojosa, the chairman of the Texas Democratic Party, who was one of many prominent Latinos who lobbied the Clinton campaign hard to put Castro on the ticket.

The decision to give plum DNC speaking slots to Nevada State Sen. Ruben Kihuen and actress America Ferrara, as well as U.S. representatives Luis Gutierrez of Illinois and Joaquin Castro of Texas, was another attempt at healing the bruised feelings of Latinos.

It’s also why you saw Clinton supporters, such as Rep. Tony Cárdenas of California’s San Fernando Valley, the chair of the Congressional Hispanic Caucus’ fundraising PAC, go out of their way to praise Kaine as “a true friend and ally of the Latino community.”

Much was made at the DNC of the fact that Kaine speaks fluent Spanish.

“He has proven himself a leader through advocacy on immigration and gun reform. It has been his life’s journey to create an equal playing field for Latino families,” Cárdenas added.

Obama won 71 percent of Latino voters in 2012, according to exit polls.They are the largest minority group in the United States and their numbers are especially strong in electorally crucial states like Colorado, Florida, Nevada and Virginia.

The haggling among Democrats, however, is dwarfed by Latino antagonism to the Republican nominee.

A Pew poll in late June projected Trump winning 24 percent of registered Hispanic voters. Some Republicans celebrated that percentage because it is about the same level of support given to the GOP’s last two nominees, Gov. Mitt Romney in 2012 and Sen. John McCain, R-Arizona, in 2008. But a Wall Street Journal/NBC poll conducted in July gave Trump only 14 percent support among registered Hispanic voters.

The Journal poll also found “heightened interest in the election among Hispanics” with 72 percent saying they are following the race closely as compared to 55 percent four years ago.

The current low-level static – the Democratic establishment on one side, and Latino voters and elected officials on the other – could still blow up into a major story before November.
