Although Republicans have historically shouldered most of the blame during government shutdowns, the party appears to be gaining ground with the public in the current standoff.
GOP leaders have framed the budget impasse as avoidable and have argued that Democrats are insisting on funding healthcare benefits for immigrants in the country illegally.
The Senate on Tuesday failed to pass a continuing resolution to fund the government, falling short of the 60 votes required for approval. The measure was supported by some Democrats who crossed party lines, but it was ultimately defeated in a 55-45 vote.
As a result, the government shut down at midnight.
President Donald Trump and Vice President J.D. Vance have led Republican messaging during the standoff, portraying Democrats as responsible for the shutdown by prioritizing benefits for non-citizens.
Democrats, meanwhile, have argued that their position centers on lowering healthcare costs and restoring funding that Republicans cut from federal programs. Early polling indicates, however, that Republican messaging may be resonating with voters, the outlet noted.
