Senator Lincoln Chaffee of Rhode Island a Democrat?

According to the Associated Press, Sen. Lincoln Chaffee (Rep-Rhode Island) is looking at his party options after losing in Tuesdays mid-term elections. His options maybe liberal or democrat. Chaffee has been the most liberal Republican in his 7 years in office. He was the sole republican to vote against the War in Iraq, as well has argued several points against his fellow Republicans often with no party backing. Each party needs to secure a balance of members, some all the way to one side, some to the other and some to the middle. If members of Congress begin switching Political Parties it will cause momentous problems. I think that in the long run a change of Parties will hurt Chaffee and other Congressmen who may decide to take this path. Politicians need to start worrying about the issues, their party affiliations will not change their political agenda. Worrying about the issue is what will help politicians reelection.
