Biden has a fast start, but is he going too big too soon?

While much of the media is hailing Joe Biden as a 21st-century FDR, there are some warning signs on the horizon.

“Go big” is the unofficial slogan of the new White House, but how big is too big? Meaning, how much major change—and new spending–can the political system swallow before choking?

At the moment, the man who the pundits essentially wrote off during the early primaries is off to a reasonably strong start. Whatever you think of his liberal agenda, Biden has delivered on the intertwined issues of the pandemic and the economy, and the polls reflect that. They also reflect that he has botched the growing migrant crisis on the border.

But having pushed through $1.9 trillion in economic aid, Biden is just getting started. He plans to press for another $3 trillion in new programs, ranging from infrastructure to climate change. These are staggering numbers: the federal budget for fiscal year 2020 is $4.7 trillion. So Biden is proposing to spend a combined total greater than the country’s annual outlay for everything from Medicare to the military, and of course the feds have been in the red for decades.

The administration says the next round will be paid for by raising taxes on the highest earners as well as corporations, which saw their rate slashed from 35 to 21 percent during the Trump years. But some moderate Democrats are already pushing back on the anticipated scope of the tax hikes, which is a problem given the party’s razor-thin margins in both houses.

Beyond the big bucks and efforts against child poverty, the president is also pushing stricter gun control and comprehensive immigration reform, two of the hottest of hot-button issues. But he left the impression last week, in talking about the importance of “timing,” that he wouldn’t allow the rest of his agenda to be derailed by these thorny challenges.

Leon Panetta, Obama’s Pentagon chief, told the Post that “the biggest danger for Joe Biden is wanting to move very fast without…
