Can Democrats hold together? Biden's agenda depends on it

House Speaker Nancy Pelosi likes to say the Democrats' diversity is its strength and unity is its power

WASHINGTON -- It’s one of House Speaker Nancy Pelosi’s favorite sayings, a guidepost for Democrats in trying times: "Our diversity is our strength. Our unity is our power.”

But as Democrats try to usher President Joe Biden's expansive federal government overhaul into law, it's the party's diversity of progressive and conservative views that's pulling them apart.

And only by staying unified does their no-votes-to-spare majority have any hope of pushing his rebuilding agenda into law.

Biden will set traveling to Michigan on Tuesday to speak directly to the American people on his vision: It's time to tax big business and the wealthy and invest that money into child care, health care, education and tackling climate change — what he sees as some of the nation's most pressing priorities.
