How strong is Biden's mandate for change?

Polls reveal that the newly-inaugurated president has quite a lot of leverage

The fireworks celebrating Joe Biden’s inauguration as president lit up the view of the night sky from my balcony a little before 10:00 PM last night. Though I live a few miles away from the National Mall, the energy emanating from Washington was nevertheless palpable. For many, yesterday was an end to mourning in America.

The demand for a progressive agenda on Capitol Hill had begun about five and a half hours before the fireworks. That’s when Vice President Kamala Harris swore in three new Democrats to the Senate (one as a replacement for her vacating her California seat) and officially gave the party control of the barest of majorities in the chamber. As of about 4:40 PM yesterday, Democrats controlled both chambers of Congress and the presidency.

But what will lawmakers do with this power? How will they perceive a public mandate for change, if they perceive one at all? Let's take a look at some early polling data on the fledgling Biden administration.
