A lot is squeezed into President Joe Biden’s new 182-page budget proposal, which the president describes as “a blue-collar blueprint to rebuild America in a fiscally responsible way.”

Congress is unlikely to pass all, or even most, of the $6.88 trillion budget as written. Still, presidential budgets are important: They tell lawmakers and voters about an administration’s political priorities. And even though Congress often simply ignores major portions of the request, the president’s budget can still serve as a starting point for legislative talks. Last year, the White House’s priorities for an infrastructure deal influenced the final package Congress ultimately passed.

This year, as Democrats no longer have control of Congress, the resulting budget document reflects both political pragmatism and political ambition. It also gives the clearest glimpse yet into how the White House plans to position itself in the upcoming fights around the debt ceiling and the 2024 reelection campaign. Biden is embracing the rhetoric of fiscal responsibility and national security, domains that have historically been Republicans’ turf. But he is doing so while rejecting any calls to roll back the welfare state. Instead, the budget lays the groundwork to expand it.

In addition to calls for increased military spending and new investments in the social safety net, the Biden budget aims to protect programs like Medicare and Social Security, largely by promoting new taxes on corporations and the richest Americans.
