Having a new representative in Congress is always an adjustment. Two weeks ago, when the 113th Congress began its first session, Ames, along with northern and northwestern Iowa, became the constituents not of the level-headed Tom Latham, but of a man who has a reputation as something of a radical, Steve King.

Representation in a republic the size of the United States is essential, and we have a rich heritage of it. Indeed, the nature and definition of representation was a key part of the debates on the Constitution. Speakers at the Constitutional Convention in 1787, the Constitution’s proponents the Federalists, and its opponents the Anti-Federalists all agreed: In the words of the minority at Pennsylvania’s convention, who voted against ratification, representatives ought “to possess the same interests, feelings, opinions, and views, which the people themselves would possess, were they all assembled.”

For all the quotations of the founding generation that permeate politics, if one thing has remained unchanged since 1787-1788, it is the definition of representation. Yet clarion calls and general derision against the buying of politicians or electoral votes through “special interest” political action committees or out-of-state campaign donations often sound out in the cacophony of political discourse.

For example, two weeks after this year’s elections, The New York Times argued that, in state judicial elections, “The dominant role played by special-interest money … has severely weakened the principle of fair and impartial courts.” After a shooting at an elementary school in Newtown, Conn., The New York Times editorialized on the National Rifle Association, “Businesses and special-interest groups often cloak their profit motives in the garb of constitutional rights — think Big Tobacco and its opposition to restrictions on smoking in public places and bold warnings on cigarette packages.”

Every citizen ought to have such concerns. One of the ways in which we can measure how much heed a candidate might pay his or her constituents, if elected, is the source of his campaign money.

The 2012 election for our Congressional district pitted Steve King for the Republicans against Christie Vilsack for the Democrats. Both candidates had their faults but, if there is a carpetbagger in the race, Vilsack is it. The spreadsheets I compiled will be posted online, but a summary of the data is as follows.

King received a total of $2,738,250 in itemized donations. Individuals contributed $1,903,185 of that figure, or 69.5 percent of the total. Party committees contributed $32,656, or 1.2 percent of the total. Other committees (PACs, etc.) contributed $802,409, or 29.3 percent of the total.

Overall, 51.3 percent of King’s itemized campaign contributions came from out-of-state sources. His campaign received 16 percent of its money from in-state sources he did not represent in his old district or would not represent in his new one, and 32.7 percent of its money came from sources located in areas he either had represented in the past or would be charged with representing should he have won the election.

Vilsack received a total of $2,583,241 in itemized donations. Individuals contributed $2,031,179, or 78.6 percent of the total. Party committees contributed $15,382, or 0.60 percent of the total. Other committees (PACs, etc.) contributed $536,680, or 20.8 percent of the total. It is interesting to note that, although 78.6 percent of itemized contributions to Vilsack came from individuals, residents of other states made 59.9 percent of her individual contributions, or 47.1 percent — the largest by far — of total contributions.

Overall, 66.8 percent of Vilsack’s itemized campaign contributions came from out-of-state sources. Her campaign received 21.9 percent of its money from in-state sources King did not represent or that Vilsack would not represent if elected, and 11.3 percent of Vilsack’s itemized campaign money came from sources located in areas either King had represented in the past or would represent if victorious.

When so much campaign money is from sources outside the constituency, is it possible for an officeholder to represent the combination of people, interests, and perspectives swirling around in that constituency? Or is the representative merely a placeholder for a national party ideology? Such questions as these are among those that voters should ask themselves. If the people truly are to hold their representatives accountable and capture the essence of a republican government, they must be able to choose from a field of representatives who receive only 11.3 percent — or even 32.7 percent — of their campaign funding from the people who live in the place they will represent.
