Burlington, Vermont | Bernie Sanders is vowing to press ahead with his presidential campaign at least long enough to debate Joe Biden this weekend, even while acknowledging his deficit in the Democratic race may be insurmountable.
The Vermont senator on Wednesday (Thursday AEDT) offered no further details on what his campaign may look like before or after he and Biden - the last two major candidates vying for the Democratic presidential nomination - spar on Sunday night (Monday AEDT) on stage in Arizona.
