The Judiciary Committee member told "Fox & Friends" that while he still remains personally opposed to Kavanaugh's nomination to the court, he expects Republicans to have the necessary votes for the judge's confirmation.
"I think this will be a very close vote. It hangs by a few undecided Democrats and Republicans. I haven't read this report yet, [but] if I were to just guess today, he would be narrowly confirmed," Coons told the Fox News hosts.
But Coons also said he remains convinced that Kavanaugh's views on presidential power, such as questions over whether a president can be under criminal investigation, were "beyond the mainstream" of acceptable judicial views.
"In my view, the jurisprudence of Judge Kavanaugh is well outside the mainstream," Coons said.
"I think his views on presidential power and individual liberty are beyond the mainstream of American jurisprudence. I don't think that's the case with [Justices] Kagan and Sotomayor, but my friend Sen. [Lindsey] Graham [(R-S.C)] has made that point to me personally that in his view the confirmation process has gotten away from looking at credentials and credibility, and into ideology," Coons added.
Coons's comments came amid the FBI's submission of its supplemental investigation into Kavanaugh's background to the White House and Senate on Thursday, with senators trading off one copy of the report in a classified materials room every hour.
Democrats including Coons have raised concerns about the investigation, which some say was restricted by the White House in a way that tarnishes the report's credibility.
