Democratic Presidential Contenders Spar Just Ahead of New Hampshire Vote Ken Bredemeier WASHINGTON - Democratic presidential contenders jabbed at each Sunday two days ahead of the crucial New Hampshire party primary, attempting to undercut each others' credentials to take on Republican President Donald Trump in the November national election. Both former Vice President Joe Biden, now in a fight for his political life, and ex-South Bend, Indiana, Mayor Pete Buttigieg claimed on ABC News' "This Week" show that the race against Trump will be more difficult to win if Sen. Bernie Sanders of Vermont, one of the leading Democratic contenders, is the Democratic nominee because he is a self-declared democratic socialist. New day-to-day tracking polling in the rural northeastern state showed Sanders leading Buttigieg in a top pairing, with Biden and Sen. Elizabeth Warren of Massachusetts in a clear second tier standing and Sen. Amy Klobuchar of Minnesota trailing further in fifth. Tuesday's vote comes a week after Buttigieg edged Sanders in the farm state of Iowa at Democratic caucuses in the race for eventual delegates to the party's July national presidential nominating convention, with the other three candidates trailing well behind. .
