WASHINGTON (Reuters) - U.S. Sen. Lincoln Chafee (news, bio, voting record), a Republican moderate from Rhode Island, said on Monday he might not vote for President Bush (news - web sites) in the Nov. 2 election.

Chafee stressed, however, that he has no plans to bolt his party, and that if he does not back Bush he will write in the name of another Republican.

His spokesman Stephen Hourahan said afterward that if Chafee does write in a name it would be that of Bush's father, former President Bush.

"I'll look at my options," Chafee said in a brief interview on Capitol Hill after discussing his indecision about the current president earlier in the day with reporters in his home state.

Asked if he might not vote for the president, Chafee said: "That's accurate." His office said this has been his position for months, though it has gotten little, if any, attention in Washington.

"There is no secret that on some very important issues I have difference with the current administration," Chafee said, listing abortion rights, the environment and war in Iraq (news - web sites).

"Like all Americans we are looking for some answers to key questions in the weeks ahead," Chafee said. "You wait until November 2 and make your choices."

On the other side of the aisle in the Senate, Democratic Sen. Zell Miller (news, bio, voting record) of Georgia has long backed Bush over his own party's nominee, Sen. John Kerry (news - web sites) of Massachusetts.

Chafee's comments on Monday drew mixed reaction from fellow senators.

"It's unfortunate," said Sen. Kit Bond, a Missouri Republican.

"He is a gutsy and principled guy," said Sen. Thomas Carper (news, bio, voting record), a Delaware Democrat. "He marches to his own drummer."

"He is a good fiscal conservative," Sen. Lindsey Graham (news, bio, voting record), a South Carolina Republican, said with a chuckle.

"What I like about him is that he can be a Republican senator and at the same time say he is unsure about a Republican president," Graham said. "He is a breath of fresh air in politics."

Commentary:
I like this story because it proves once again that the media is biased towards republicans. Senator Chafee has been saying all summer that he won't vote for Bush but the media has kept it well hidden, until today. Good for Senator Chafee. It'd be nice to see more republicans speak out against Bush.
