Mike Allen reports at Axios:
A wave of announcements, like the one Sen. Elizabeth Warren made on New Year’s Eve morning, is planned for the next few weeks. The hopefuls need to raise money, and need an organization for housing the aides they want to hire to take them off the hot 2020 job market.
Look for announcements this month by Sen. Cory Booker of New Jersey, Sen. Kamala Harris of California, Sen. Kirsten Gillibrand of New York, Colorado Gov. John Hickenlooper and likely others. I’m told that “the Bs” — Biden, Bernie, Beto and the billionaires, including Mike Bloomberg — can wait longer because they’ll be able to quickly raise money.
