Republican state Rep. Jaime Herrera’s congressional campaign has accused Herrera’s Democratic opponent, Denny Heck, of “selective amnesia” for his Tuesday statement to The Columbian that he never supported an income tax while he served in the Legislature from 1977 until 1985. Heck denied — and his campaign continues to deny — voting for an income tax in response to a flood of TV ads and fliers funded by Republican Party organizations that declare he was a big spender and, among other things, “even fought for an income tax” during his legislative career.Herrera’s spokesman, Casey Bowman, said the record is clear. “The amnesia appears to have erased (Heck’s) memory of voting for taxing and spending increases that includes his support of a state income tax, a vote for the largest tax increase since Washington’s statehood, taxes on businesses, a gas tax, and others,” Bowman said in a statement.As evidence that Heck supported an income tax, he provided a clip from the Nov. 23, 1982, edition of the (Spokane) Spokesman-Review that quotes Heck saying that a citizen committee’s proposal to add personal and corporate income taxes to the state’s tax system “represents a highly responsible effort by a group of very civic-minded people” to reform the state tax code. Heck served on the bipartisan Washington Tax Advisory Council that year and cast a vote on the council to recommend the flat-rate tax.Heck told the Spokesman-Review he planned to sponsor legislation the following year to submit the proposed constitutional amendment to voters. He co-sponsored such a bill in the 1983 session, but it never emerged from committee in either the House or the Senate.
