WASHINGTON (CNN) - As President Bush's low popularity ratings looms over the Republican race, the White House hopefuls have said little during past debates about their commander in chief.
But Colorado Rep. Tom Tancredo addressed what he thought Bush's role should be after he finishes his second term.
"Some time ago, 2003, I think it was, I got a call from Karl Rove who told me that because of my criticism of the president, I should never darken the doorstep of the White House," he said.
He added, "As president, I would have to tell George Bush exactly the same thing that Karl Rove told me" because he was so disappointed in various aspects of the President's program, including education and the prescription drug bureaucracy, as well as immigration reform.
Former Bush cabinet member Tommy Thompson said: "I would certainly not send him to the United Nations."
Thompson said the President's strengths of honesty and perseverance would be best used in touring America talking to the country's youth.
"I think he could be a wonderful spokesperson" for the virtues of public service, he said.
