WASHINGTON (AP) — Montana Sen. Max Baucus said Wednesday that he will not support Supreme Court nominee Samuel Alito because he is too far outside the mainstream of judicial thinking.

‘‘He’s just not right for Montana, he’s just not right for America,’’ Baucus said after meeting Alito in his Capitol office.

Baucus, a Democrat, said he is concerned that Alito leans toward giving too much power to the executive branch, has wavered on the right to privacy and has praised judicial nominee Robert Bork.

Alito in 1988 called Supreme Court nominee Bork ‘‘one of the most outstanding nominees of this century,’’ though he tried to suggest in Senate Judiciary Committee hearings that he doesn’t necessarily agree with or model himself after the conservative judicial icon summarily rejected by the Senate.

Baucus said he was also concerned about Alito’s membership in an organization that discouraged the admission of women and minorities at Princeton University.

The senator said Alito is competent, intelligent and ethical, but did not meet all of his standards.

He contrasted Alito with Chief Justice John Roberts, who won Senate confirmation last fall. Baucus voted for Roberts, who he said was more consistent and forthcoming.

‘‘There are differences between the two which gave me some concern,’’ Baucus said, adding that Alito was vague on many issues when the two met Wednesday.

‘‘He is very polished, he answered all of the questions I was going to ask,’’ he said. ‘‘There is just a little too much inconsistency.’’

The Senate Judiciary Committee is scheduled to vote next Tuesday on Alito’s nomination to replace Justice Sandra Day O’Connor, who often casts the swing vote on controversial cases. Senate Democrats were meeting Wednesday to discuss the nomination.

The state’s other senator, Republican Conrad Burns, said last week that he will support Alito.
