Both former candidates' decision to throw their support behind Biden will assuage concern that the moderate candidates were splitting the vote, weakening their position against Sen. Bernie Sanders to their left. 

The former mayor made the decision to exit the race following his disappointing fourth-place finish in the South Carolina primary, where exit polls indicated he won the support of just 3% of the state's black voters.

Pete Buttigieg Feb 28Business Insider

While Buttigieg had impressive showings in the first two voting contests, winning the Iowa caucuses and finishing second place in the New Hampshire primary, his support didn't translate to the more diverse electorates in Nevada and South Carolina, where he failed to gain traction among Hispanic and black voters.

Buttigieg ran on moderate policies, similar to Biden's, including adding a public option to Obamacare — or "Medicare for all who want it" — as an alternative to single-payer healthcare, and more conservative approaches to student debt and taxes, while lamenting the national debt.

He told Insider in a March interview that he hoped to reframe the policy debate around values and make pragmatic the new progressive.

Like Biden, Buttigieg repeatedly attacked Sanders and Sen. Elizabeth Warren for running on a policy agenda he deemed too radical for most Americans. 

"He's talking about either a revolution or status quo and there's nothing in between," Buttigieg said of Sanders. "We can't defeat the most divisive president in modern American history by tearing down anybody who doesn't agree with us 100% of the time."
