Hailing from some populous state as a longtime member of Congress and an envoy to Russia and England, Buchanan had many attractive political assets. In essence, Buchanan gave the delegates the kind of hope that seemed in short supply during the tumultuous mid-1850s. A smooth, pleasantly dull conservative, he upset few people. Above all, Buchanan was from the North, yet he maintained ideological ties to the South—a "doughface" in the slang of the day. Buchanan forces quietly told the Douglas men that cooperation from the "Little Giant" would enhance his chances for 1860, and Douglas withdrew from the race. "Old Buck" got more ballots than any other candidate in the first round, and he clinched the Democratic nomination with the requisite two-thirds majority on the seventeenth ballot, an easy victory during that bitter era. John C. Breckinridge of Kentucky received the party's vice presidential nod.
