Sen. Tim Johnson may still be recovering from emergency brain surgery, but that hasn't prevented his campaign from ann hauling in some $600,000 in the last quarter.

The ailing Senator's tally comes mostly from the help of colleagues, who have helped him pull in a total of $1.3 million this year, leaving him with $1.8 million cash on hand.

Johnson is expected to be a top target of the GOP this year. But the only candidate to make serious noises about challenging him, State Rep. Joel Dykstra, isn't seen as a first-tier candidate.
