Even as President Trump and top Republicans contend that only big-spending, liberal-leaning states are to blame for their mounting budget woes, a Washington Post review found the economic havoc wrought by the coronavirus is far more widespread — saddling Democratic and Republican mayors and governors alike with souring finances and major revenue gaps. Some local governments have already started laying off or furloughing thousands of their workers, and the numbers are likely to grow markedly in the absence of federal aid.

Among municipalities, the new budget cuts could be profound: Between 300,000 and 1 million public-sector workers could soon be out of a job or sent home without pay, according to a new estimate from the National League of Cities. The steep reductions in staffing levels could affect education, sanitation, safety and health, local leaders warn, potentially leaving critical public services in utter disarray.

For governors, mayors and other top local officials, their economic troubles stem from the precipitous drops in revenue that have come as a result of shuttered businesses and sharp decreases in shopping and travel. The extent of the disruptions are poised to reach a level not seen since the Great Recession more than a decade ago, a reality that has prompted many city and state leaders to plead with Washington for help.

But their public quest for federal cash has been met with staunch political resistance from Republicans, including Senate Majority Leader Mitch McConnell (R-Ky.), who at one point suggested states should have the option of falling into bankruptcy. Top Trump administration officials have echoed that skepticism and signaled that any aid would come with conditions: On Tuesday, for example, the president said he would only approve money if states cracked down on immigration policies in “sanctuary cities.”
