As his volunteers (led by youth coordinator Sam Brown) went door to door in New Hampshire, and as the media began paying more serious attention to the senator, McCarthy began to rise in the polls. When he received 42% of the vote to Johnson's 49% in the March 12 New Hampshire primary (and 20 of New Hampshire's 24 delegates to the Democratic convention), it became clear that there was deep division among Democrats about the war. By this time, Johnson had become inextricably defined by Vietnam, and this demonstration of divided support within his party meant his reelection (only four years after winning the highest percentage of the popular vote in modern history) seemed unlikely. The folk trio Peter, Paul and Mary released a record "Eugene McCarthy For President (If You Love Your Country)", endorsing McCarthy, who they said had stood alone against Johnson over "more timid men" now echoing him.
