The ouster of Ron Paul’s backers from Iowa’s Republican Party leadership this weekend might help the state party raise money.

Mr. Paul, the champion of libertarianism and former Texas congressman, is the father of Senator Rand Paul, Republican of Kentucky, a possible presidential candidate. In describing Saturday’s move, Jennifer Jacobs of The Des Moines Register said the party was trying to build a broader base, with less focus on “pet liberty-movement issues,” adding, “Big donors who closed their checkbooks may start giving money to the state party again.”

Here’s how bad the situation has been for the Iowa G.O.P.: The $129,843 raised in the first three months of 2014 is the lowest amount in a year without a presidential election since at least 2002. Last year, the party raised less than half of what it did in 2005.
