To the Editor:

Paul Krugman is right on the money (“Pieces of Silver,” column, Aug. 12). Whether one accepts or rejects Donald Trump, embracing the conduct of congressional Republicans is just as costly to America.

Limiting taxes on the wealthy and special interests has been the central aim of Republicans in Congress for decades.

Many in the business community claim to support immigration reform, gun violence prevention, scientific research, women’s right to choose, L.G.B.T. equality and environmental protections. Yet the tax issue “trumps” all, as their support of congressional Republicans proves.

There’s not a dime’s worth of difference between Donald Trump and what Republicans in Congress have been advancing for years. Mr. Trump’s candidacy has exposed the same moral compromise that the G.O.P. establishment and business community have always made to protect special interests and the wealthy.
