There have been occasional calls for Mr Biden to step aside, like Johnson. But there is no sign that he is willing to do so and no guarantee that the Democrats would end up with a stronger candidate if he did. For that reason, although many Democratic operatives have grave misgivings about his candidacy, most are keeping quiet. Sitting presidents do not tend to abandon bids for re-election. The most recent to do so was Lyndon Johnson, in 1968. And that is a year that his party, the Democrats, would rather forget. Johnson was unpopular. Do you think that democrats’ lack plan B except Joe Biden for presidency ?
