Donald Trump made an unprecedented move this week that could go a long way toward shoring up his support among the Republican Party establishment.

The presumptive Republican nominee on Wednesday released a list of judges he would consider for Supreme Court nominations in a theoretical presidency. It's a step that no prior presidential candidate has taken.

But shortly after his list of 11 potential nominees went public, he received ringing praise from all sides of the party.

House Speaker Paul Ryan — the top-ranking Republican in Washington who made waves by initially declining to endorse Trump — said the list of names was a ''very good step in the right direction."

The chairman of the Senate Judiciary Committee, which has oversight over the Supreme Court nomination process, was equally impressed.

In a Wednesday statement, Iowa Sen. Chuck Grassley said Trump's list was composed of judges who "understand and respect the fundamental principle that the role of the courts is limited and subject to the Constitution and the rule of law."

Grassley said Trump's list goes to show the American people that they have "a voice in the direction of the Supreme Court for the next generation."

Trump said in a statement that the list of judges is "representative of the kind of constitutional principles I value."

He has attempted to seize on an issue that could be the deciding factor for Republicans torn about whether to support him over likely Democratic nominee Hillary Clinton. He said in a speech Friday that as president, he could appoint as many as five justices. And with four justices currently on the bench at least approaching the age of 80, it's not as far-fetched as it seems.

GOP strategist Matt Mackowiak told Business Insider that the release of potential Supreme Court nominees was one of the most important moves Trump could make ahead of the fall election.

"I think it sort of helps some of the conservative angst out there and it addressed one of the biggest problems with a Republican supporting Hillary, and that is the Supreme Court," said Mackowiak, who founded the Washington-based political communications firm Potomac Strategy Group.

"He can do himself a lot of good if he keeps pulling moves like this out," he continued. "So, the VP search is part of that, the future cabinet is part of that, but the Supreme Court is a lifetime appointment. It's really, really important."

Mackowiak said he considers himself an undecided voter at the moment, although that does not mean he's considering voting for Clinton. The list of potential nominees helped him to view Trump in a more favorable light, though he's still not hopping aboard the Trump train.
