Liberal Republican party
Ulysses S. Grant beat Horatio Seymour in 1868 and Horace Greeley in 1872 (Greeley carried six states, but died between the November election, when electors are chosen, and the December election, when the electors cast their votes).
The Whigs and Democrats avoided and evaded the issue of slavery in the election of 1848 by splitting down the middle on who was for and who was against slavery. Whigs and Democrats in the South wanted to keep slavery. Whigs and Democrats in the North wanted to abolish slavery.
Democrats are against border control.
Ulysses S. Grant
His opponent in 1868 was Horatio Seymour from New York. In 1872 Horace Greeley, also from New York, ran against him. (Greeley died after the popular election but before the electoral college voted, so it might have been legally interesting if Greeley had won. )Victoria Woodhull also ran in 1872, but she was too young to be president, did not appear on any ballots and did not get any votes, so some doubt that she was a serious candidate.
Henry Clay ran for the National Republicans against Andrew Jackson. The party was formed against Jackson Democrats and soon grew into the Whigs.
NO
Truman was not expected to win Truman's own party split over his candidacy Democrats had put up two candidates against him
Horace Greeley
Horace Greeley
Horace Greeley
The Democrats were in disarray and did not nominate a candidate, but they endorsed Horace Greeley of New York, who had been a Republican, was against big business, was against slavery and for protective tariffs and but was considered by the South to be better than Grant. Grant was favored by business interests and was still a popular war hero. Grant won easily.
