From the Washington Post, this can be viewed as a story about how parties seek to recapture control of the nominations process in an age of primaries:

With presidential primaries looming, there is only one name on the official list of Democratic presidential candidates in Florida — President Biden — a move that angered the incumbent’s long-shot challengers, who say they’re being unfairly left out.

The decision is the latest setback for Rep. Dean Phillips (D-Minn.) and Marianne Williamson, both of whom trail Biden in public polling and fundraising.

Under Florida rules, the state’s party votes on who will appear on primary ballots. Florida’s Democratic Party said in a statement Friday that the executive committee voted unanimously late last month to name Biden, and only Biden, to its list of candidates.

If a presidential primary has a single candidate, state election law says that the uncontested race will not appear on the state’s primary ballot.

“Americans would expect the absence of democracy in Tehran, not Tallahassee,” Phillips said in a statement. “Our mission as Democrats is to defeat authoritarians, not become them.”

Williamson said in a statement that the move in Florida is meant to help Biden win the nomination “without any opposition.” Both candidates’ statements said their campaigns are considering legal options to gain access to Florida’s ballot.

In its statement, the Florida Democratic Party said the party’s actions were part of a “standard process,” and that “it is not uncommon for an incumbent President to be declared the automatic winner of a presidential primary.” The last time it happened was in 2012, when President Barack Obama ran for reelection, according to the statement.
