Biden allies see O’Rourke as a clear threat

“If both of them run, and there’s a good chance they both will, I think it spells trouble for Biden,” said one longtime aide to the former vice president.

There are a series of reasons why political observers think the upstart Texan could represent an existential threat to Biden’s presidential hopes.

The biggest is that O’Rourke appeals to former President Obama’s network of former aides and donors, who are searching for a candidate to back for the first time in more than a decade.

Dan Pfeiffer, the former Obama senior adviser who co-hosts the “Pod Save America” podcast, wrote a piece for Crooked Media last month on why O’Rourke should run.
