Arizona Rep. Ruben Gallego issued challenges to the state's Republican senators on Thursday, urging them to at least consider whoever President Barack Obama nominates for the U.S. Supreme Court vacancy.

"As a member of Congress who was elected to do my job, I take my constitutional duty seriously. It's time for Arizona Sens. John McCain and Jeff Flake to take their jobs seriously," Gallego said in a press statement. "The Constitution gives the President the responsibility to nominate Justices to the Supreme Court, and it gives the Senate the job of considering that nominee. There are no exceptions for election years."

The congressman went on to call McCain and Flake's refusal "just another example of GOP destruction and obstruction."

Public Approval for a Nominee

Gallego's message was part of a Mi Familia Vota press call that included pro-nomination stances from Latino advocacy groups, a Deferred Action for Childhood Arrivals (DACA) recipient and one of the state's former assistant attorney generals. It comes on the heels of a Wall Street Journal survey indicating 55 percent of registered voters disapprove with efforts to block Justice Antonin Scalia's replacement.

More than four-in-five people said they "strongly disapprove" of Republican tactics, as did 57 percent of participants who identified as Independent.

Samantha Pstross, Executive Director of the Arizona Advocacy Network, said Arizonans fall along those lines. She believes the issue is big enough for McCain to lose re-election in November.

"We can see the same trend across race, 70% Hispanics and 61% of whites disapprove of Senator McCain right now," Pstross said. "If Senator McCain wants to keep his job, it's clear that he needs to do his job and fill that seat."

Finding a New Supreme Court Justice

Obama says it is his constitutional duty to appoint a new Supreme Court Justice before his term ends in January. GOP lawmakers would rather hold off until after the general election, when they anticipate either Donald Trump or Ted Cruz wins the presidency.

There was a period when Nevada Gov. Brian Sandoval seemed like an ideal candidate for both parties, but the Republican Latino shot down rumors days after his name began circulating.

The glaring hole in the country's highest court means a slew of high-profile cases -- including Obama's executive action on immigration -- will either be postponed or heard by an eight-judge panel. If it comes to the latter, the previous court's decision will be upheld.

"I know how critical it is for our judicial system to have a fully operational Supreme Court to deliver justice and interpret the law for the entire nation, and how important it is for everyone to ensure that all parties have a judicial system that is free from political interference," said Vince Rabago, former Arizona attorney general.

He added, "To inject the politics of election year obstruction only proves that our elected leaders in Washington DC are not working for the people of this great country who elected them."
