U.S. Sen. Cory Booker is set to headline the Colorado Democratic Party’s annual fundraising dinner in March in Denver, the party said Tuesday. The popular former two-term mayor of Newark, N.J., was elected in 2013 to the U.S. Senate in a special election and has been twice reelected to full terms. In 2020, he was among nearly two dozen Democrats who sought the presidential nomination but dropped out of the primary before the Iowa caucuses.
