From Political Extra:
[Sen. Collins] raised $963,260, bringing her total to $5.52 million. She has $4.51 million in cash-on-hand.Collins has opened up a sizable cash-on-hand lead over Rep. Allen.
Still, as we've noted in the past, both candidates are going to have more than enough money to compete. (Of course, it's always better to have more cash than less.)
UPDATE: As Eric Kleefeld at Election Central notes, this is already the most expensive Senate campaign in Maine history.
And it's just getting started.
UPDATE UPDATE I've corrected the post's title which originally referred (incorrectly) to Q4.
