From a New York Times conversation between Gail Collins and Bret Stephens headlined “Biden-Trump, the Sequel, Has Quite a Few Plot Twists”:

Bret Stephens: Hi, Gail. A recent CNN poll shows that 20 percent of Democrats favor Robert F. Kennedy Jr., for the party’s nomination, 8 percent want Marianne Williamson and another 8 percent want someone else. That’s 36 percent saying they aren’t thrilled with the presumptive nominee. Do you think this is some kind of polling fluke or an ominous political sign for Joe Biden?
