The conservative Americans for Prosperity-Nevada is pressuring Rep. Steven Horsford and Sen. Catherine Cortez Masto to oppose renewing a raft of corporate tax breaks known as “tax extenders” as well as the reauthorization of the Export-Import Bank, which helps business finance exports.

“All Nevadans deserve the chance to compete on a level playing field, but that won’t be so until the government favoritism that currently plagues Washington in the form of ‘tax extenders’ and the Export-Import Bank comes to an end,” AFP-NV State Director Juan Martinez said in a statement. “Through these policies and others like it, the government picks winners and losers and rigs the economy in favor of special interests and the well connected."

Conservatives, like AFP, which is funded by political activists David and Charles Koch, have opposed tax extenders and the bank as corporate welfare.

The group contends the issue resonates with voters, citing a Washington Post/ABC News poll from April found that 62 percent of Americans said they thought the U.S. economic system mainly benefits those in power while only 34 percent who said it mainly benefits all people.

Horsford sits on the Ways and Means Committee, which has jurisdiction over tax policy in the House. Cortez Masto sits on the Senate tax writing panel, the Finance Committee, and the Banking Committee, which oversees the Export-Import Bank.

AFP’s campaign will include direct mail and digital ads, the group said. Horsford is up for re-election next year, but Cortez Masto, who as chairman of the Democratic Senatorial Campaign Committee is working to elect more Democrats to the Senate in 2020, won’t face voters until 2022.

Tax extenders are often renewed by Congress retroactively and are expected to be considered by the tax-writing committees and likely by the full House and Senate before the end of the year. Similarly, Congress will have to act before the end of the fiscal year, Sept. 30, to reauthorize the Export-Import Bank.
