The difference is that an Coverdell and Miller were statesmen, and Isakson will never be.
I voted for Isakson because he is better than Majette, but that is the only reason. He is better than Majette because she is a nut case, almost as bad as McKinny. On the other hand, she would be easier to defeat in the next election, but she could do a lot of damage in 6 years.
Maybe Bush will appoint Isakson to some useless post during the next 4 years and we can replace him with a Republican.
However, remember, we are dealing with retaining the Majority of the Senate, which in turn, effects chairmenships of committees.
We do not want Ted Kennedy, Hillary and Kerry heading any committees.
