DFL-endorsed Rick Nolan, taking aim at freshman Minnesota Republican Chip Cravaack in one of the Democrats' best congressional pick-up opportunities in the nation, posted the weakest fundraising total Sunday of the leading contenders in the race. The three-term former congressman, who last served in 1981, pulled in $127,721 for the second quarter, less than a third of the incumbent's haul of $393,753. Nolan, running with the support of ousted DFL congressman Jim Oberstar, also is fending off a primary challenge from former DFL state Sen. Tarryl Clark, who raised $232,128 in the three-month period ending June 30. Nolan bested only former Duluth City Council President Jeff Anderson, who took in $50,095 over the same period. Nolan, Clark and Anderson are facing off in an Aug. 14 primary. Nolan's total leaves him entering the mid-summer campaign season with $93,435 in the bank, compared with $898,681 for Cravaack and $259,022 for Clark. Only Anderson, considered the dark-horse in the race, has less, reporting $18,352 in cash on hand. Nolan and Anderson were the last to make their numbers public. Late filings are rarely a sign of fundraising success. Nolan's campaign, with the smallest second quarter total to tally (other than Anderson), waited until late Sunday to file, several days after Clark and Cravaack made their numbers public. Nolan's latest report brings his fundraising total in the race so far to about $330,000, far behind Cravaack, at $1.4 million, and Clark, with a little over $1 million. Anderson still lags in total fundraising at about $162,277.
