the debate, 21% said buttigieg did the best. trailing only warren. nevada voter shelly elmer is one of them. i m a supporter. i m here. all in for pete. and when did you decide that? the last debate. and what was it about the last debate that sold you? he was tough in a nice, respectful manner. reporter: but matt de falco, a fellow veteran felt the tone debating gun control with beto o rourke was too combative. i don t need lessons from you on courage. political or personal. it wasn t bold to me. it just felt unproductive when he talked about, you don t have to judge my character. we know who mayor pete is. got a ton of respect for him, but that didn t feel right either. are you concerned this new tone is going to alienate some voters? as we ve seen, the debates thop grow support for the campaign. and it s still me, but sometimes you have to point out differences.
