Those expecting Joe Biden’s presidential candidacy to flame out any day now will have to keep waiting. The former U.S. vice president survived another Democratic debate on Thursday largely unbloodied and unbowed, leaving those on the margins of the race for the party’s 2020 nomination wondering if their time to gain ground on the front-runner is running out. If anything, the third Democratic debate in Houston was notable for how few of the nine other candidates took hard swings at Biden, a marked contrast from earlier debates when his record was more directly challenged.
