Bush offers hints of his views on 2008 election

WASHINGTON (Reuters) - President George W. Bush stayed mum on his preferred candidate in the U.S. presidential race on Thursday, but dropped plenty of hints about what he thinks are the top qualifications for the job.

Despite two successful White House campaigns of his own, Bush refused to be "opiner-in-chief," fending off reporters' attempts to get the Republican president involved in the 2008 race to succeed him.

But he couldn't resist offering up a few opinions on the qualities he believes are essential to the job.

Firm principles matter most, he said. Getting "unvarnished" opinions from policy advisers was also crucial.

Bush is in a unique position among modern presidents -- he lacks an heir-apparent because his vice president, Dick Cheney, has made clear he has no intention of running.

He will campaign for whomever wins the Republican nomination in the general election contest with the Democratic candidate. The months-long selection process begins in two weeks with the Iowa caucus.

"I just want to know whether or not somebody's got a sound set of principles from which they will not deviate," Bush said. "What are the principles that you will stand on, in good times and bad times? What will be the underpinning of your decisions?"

He said he would also ask, "What process will you have in place to ensure that you get the, you know, unvarnished opinion of advisers?"
