Talk of unity comes easy to seasoned politicians...It rolls off their lips. During last night's speech Biden could have given mention to the Warp Speed project which produced the vaccines in record time. He didn't have to mention Trump by name, but just a momentary passing reference to the contribution by the previous administration.
During the campaign and before the inauguration, Biden spoke often about the need to unify the nation. Last night Biden passed on an appropriate opportunity to do so.
