Former Democratic presidential candidate and U.S. Sen. Bob Kerrey is heading into another week with no decision on whether he'll seek Nebraska's open Senate seat.

That has some wondering if he's waiting to see if Republican Gov. Dave Heineman will join the race.

Nebraska election law requires state office holders to file for election -- even if it's for a different office -- by Feb. 15 this year. Non-office holders, like Kerrey, have until March 1 to file.

Most think Heineman would be an easy winner if he ran for the Senate seat being vacated by Democrat Ben Nelson, but the governor
has maintained that he won't run.

If Kerrey opts to join the race before Feb. 15, Heineman would have little time to consider changing his position.
