The latest campaign disclosure reports show there’s a lop-sided fundraising race between Tom Latham and Leonard Boswell — the two incumbent Iowa congressmen who’re running against one another in November. Republican Congressman Tom Latham had nearly $2-million in cash in his campaign account by May 16th.

That was a deadline day for reporting fundraising totals. It’s six times more than Democratic Congressman Leonard Boswell had. Boswell had about $300,000 in his campaign account by mid-May.

Democratic Congressman Bruce Braley of Waterloo raised about $100,000 since April 1st. Congressman Dave Loebsack, a Democrat from Iowa City, raised about $13,000 more than that.

But former Iowa First Lady Christie Vilsack, the Democrat who plans to challenge Republican Congressman Steve King in November, raised more than Braley and Loebsack combined. Her haul in the six-week period was $230,000.

Congressman King, however, is a more aggressive fundraiser than he has been in the past, collecting nearly $373,000 dollars during that six-week period. King had about a million dollars in his campaign account by mid-May. Vilsack had about $144,000 less.

Two Republicans face off in June’s primary to win the G.O.P. nomination to challenge Braley in November. Loebsack faces a Democratic challenger in the primary who hasn’t set up a campaign website or raised enough money to require disclosing his donors.

And two Republicans are running in the second congressional district for the change to run against Loebsack in November.
