Judge Sonia Sotomayor is "within the mainstream" of jurists, a key Republican senator in her confirmation battle said Monday night.

"She's been a judge for 12 years, and when you look at her opinions, she's left of center but within the mainstream," Sen. Lindsey GrahamLindsey Olin GrahamDurbin: I had 'nothing to do' with Curbelo snub Republicans jockey for position on immigration Overnight Health Care: House passes 20-week abortion ban | GOP gives ground over ObamaCare fix | Price exit sets off speculation over replacement MORE (R-S.C.) said during an appearance on Fox News.

The comments come after a day in which Graham seemed to indicate some support for President Obama's choice to join the Supreme Court, marking a break with more conservative members of the GOP in the Senate -- including Senate Judiciary Committee Ranking Member Jeff SessionsJefferson (Jeff) Beauregard SessionsIntel leaders: Collusion still open part of investigation Republicans jockey for position on immigration Biden to Alabama: No more extremist senators MORE (R-Ala.).

Sessions said Sotomayor is "outside the mainstream" Monday morning during an appearance on CBS.

Indeed, "mainstream" was one of the top buzzwords during yesterday's opening day of hearings before the Judiciary Committee on Sotomayor's nomination.

"Her record shows that she is in the mainstream," Sen.

Graham gave Sotomayor some other Republican cover yesterday when he told the federal judge she'll likely be confirmed by the Senate, barring a "complete meltdown."
