With the election of Barack Obama, the nation is gaining a new president, but Illinois is losing its junior senator, after only four years on the job.

Gov. Rod Blagojevich can cushion that blow by selecting as Obama's successor someone who will work hard to represent all of Illinois, not simply pursue a personal agenda - or the governor's agenda.

Numerous names have been bandied about as a possible successor, but Blagojevich has given no hint of who he is considering, other than to say he is not interested in appointing himself.

Among those said to be in the running are retiring Senate President Emil Jones, Attorney General Lisa Madigan, Treasurer Alexi Giannoulias, state Director of Veterans Affairs Tammy Duckworth and U.S. Reps. Jesse Jackson Jr., Luis Gutierrez and Jan Schakowsky

Obama's formal resignation from the Senate, which took effect Sunday, does not hasten the need for Blagojevich to make a decision. It was generally accepted that the president-elect was unlikely to return to the Senate to vote.

As for a delay leaving Illinois without part of its representation, well, Obama's attendance record wasn't exactly stellar while he was running for president.

It is better that Blagojevich make the right decision rather than a rushed decision - but he shouldn't take too long. There has been plenty of time for the governor to think about this even before Election Day.

Under Illinois law, Blagojevich has complete freedom in appointing someone to fill the remaining two years of Obama's term. There is no requirement for Senate confirmation.

Blagojevich can choose to reward a crony, he can choose to do what's best for him or he can choose to do what's best for Illinois. The answer should be obvious.

Blagojevich should select someone who, as Sen. Dick Durbin said last week, "understands that there are 102 counties in the state, and that all of them need help."

Even though no independent confirmation or consultation is required, Blagojevich should converse with other state leaders, not just his staff. That should include Durbin, who said he is trying to meet with the governor. Durbin and Blagojevich reportedly have not spoken for months.

This is not a caretaker assignment; the appointee will serve for two years. The next senators should put the needs of Illinois residents first - so should the governor.
