What are Republicans offering the blue-collar voters they won in 2020?

In Washington, as Democrats advance a nearly $2 trillion economic stimulus bill, they are facing universal opposition from congressional Republicans to the package, which is chock-full of measures to benefit struggling workers a full year into the coronavirus pandemic. The bill includes $1,400 checks to middle-income Americans and extended unemployment benefits, which are set to lapse on March 14.

And at a high-profile, high-decibel gathering of conservatives in Florida last weekend, potential 2024 presidential candidates, including Mr. Hawley and Senator Ted Cruz of Texas, scarcely mentioned a blue-collar agenda. They used their turns in the national spotlight to fan grievances about “cancel culture,” to bash the tech industry and to reinforce Mr. Trump’s false claims of a stolen election.

Inside and outside the party, critics see a familiar pattern: Republican officials, following Mr. Trump’s own example, are exploiting the cultural anger and racial resentment of a sizable segment of the white working class, but have not made a concerted effort to help these Americans economically.
