The 64-year-old Harkin, by far the state's most influential Democrat, is torn on a decision that could help tip the balance in the highly competitive caucus race. He said he plans to deliberate until early next week, and then announce his decision.

******************
Harkin is a shrewd politician. Geppie is starting to tank in Iowa. Even if he wins Iowa, he has no money and no poll numbers to prove that he could win anywhere else (except maybe his home state) If Gep loses the nomination, he has no political clout (giving up his seat in the Congress) to help Harkin's with much of anything.
If Harkin was going to endorse Gep, he would have done it a long time ago. He was waiting to see who would be the most likely winner of the race.
I think that Harkin's endorsement is in the bag.
