WASHINGTON (CNN) -- Secretary of State Condoleezza Rice dismissed rumors Tuesday that she is angling to be Sen. John McCain's running mate, instead telling reporters she plans to head back to Stanford University.
Secretary of State Condoleezza Rice ruled out a McCain-Rice ticket on Tuesday.
"I very much look forward to watching this campaign and voting as a voter," she said. "I have a lot of work to do and then I'll happily go back to Stanford."
Rice served as provost at Stanford from 1993-1999, and remains a tenured professor there.
"Senator McCain is an extraordinary American," Rice also said of the party's presumptive nominee. "A really outstanding leader and obviously a great patriot." Watch Jack Cafferty weigh in on a Rice run »
Her comments come after Dan Senor, a leading Republican strategist, suggested on ABC Sunday that Rice is mounting a behind-the-scenes campaign to be McCain's No. 2
"Condi Rice has been actively, actually in recent weeks, campaigning for this," Senor, a former Bush administration official said.
On Tuesday, Grover Norquist -- conservative activist and president of Americans for Tax Reform -- lent his support to Rice as a vice presidential candidate, according to WashingtonPost.com's Mary Ann Akers.
"If her goal was to convince everyone she would be a good president and, therefore, a good vice president -- she hit it out of the ballpark," Norquist told Akers in "The Sleuth" online column.
In the column Norquist also said Rice "would be a great president. ... [a] great vice president."
McCain, meanwhile, said Sunday he had "missed those signals."

CNN senior political analyst Bill Schneider says it would be a "very difficult move" for McCain to make because it "instantly fulfills exactly the argument that Democrats are presenting ... what you're going to get is a third term of George W. Bush." Watch more of Bill Schneider's analysis »
