NASHUA/PLYMOUTH, N.H. (Reuters) - Democratic presidential candidates Bernie Sanders and Pete Buttigieg traded jabs over money and message on Sunday, two days before New Hampshire voters pick their choice to take on Republican President Donald Trump in November.

The rivals, who emerged from last weeks Iowa caucuses essentially tied, offer stark alternatives for the top of the Democratic ticket. Sanders, 78, is a U.S. senator and an impassioned progressive who has spent almost three decades in Congress, while Buttigieg, 38, is a moderate military veteran who served two terms as mayor of South Bend, Indiana.

The idea that weve either got to wait for a revolution or wait for the status quo leaves most of us out, Buttigieg said at a packed middle school gymnasium in Nashua, New Hampshire, in thinly veiled references to rivals Sanders and former Vice President Joe Biden . We need a politics that brings all of us in.

Buttigieg, who would be the nations first openly gay president, deflected attacks from his more well-known rivals as they jostled to dampen the momentum of a candidate who has surged in New Hampshire polls over the past few days.

Tuesdays primary, the second in a state-by-state nominating contest, also will test the staying power of U.S. Senator Elizabeth Warren , who finished third in Iowa, and Biden, who placed fourth. They joined the field of 11 Democratic candidates for a frantic day of campaigning ahead of the New Hampshire vote.
