Voted Jackson because, with all due respect to fiscal conservativism, this guy's cultural conservativism reached genocide levels.
All in service to the common (white) man.
Andrew Jackson was a majoritarian. He felt that the majority should always get their way, even if that meant harming a minority. This contrasts with egalitarianism, which means protecting minorities from the bigotry of the majority.
I don't think that's a fair description of Jackson's majoritarianism. Obviously if a big state like New York wanted to take away the rights of people from Tennessee, he wouldn't be down with that. Jacksonianism as a political tradition involves a fierce commitment to individual rights and opposition to elitism. Egalitarianism means equality, and Jackson believed in equality. The key question is who this equality extended to: Who are considered a part of the community who's rights must be respected, and who are outside of this community? For Jackson, it was the whites. And so protecting the interest of the smallholder white farmer meant clearing space for them to make a good living and set themselves up as free and independent people. The Whig opponents of Jackson's Indian policy had a more expensive view of whose humanity America had a moral responsibility to respect, even though they often had a more conservative understanding of equality.
