What landowner in the South after the war was "rich"?

rich landowner is the only possible answer here, but the term rich is misleading and prejucical. A damn Yankee probably wrote the question.
The Democratic party after the war made the calculated decision that in the South its best prospect was to align with the white supremacy folks. Most of these folks were not "rich" at all. Many of these folks had been poor to start with before the war, but the war reduced them to poverty, and they saw the liberation of the Negroes as a threat to their livelihood and existance. Frankly, in the South, that group is still the stew pot of racial discontent, not "rich" landowners.

During the Reconstruction era in the United States, which took place between 1865 and 1877, the Democratic Party faced opposition in the South. However, there were indeed groups of Americans in the South who supported the Democratic Party during this time. These groups included scalawags, African Americans, and some rich landowners.

To understand this, it's important to briefly explain the context of the Reconstruction era. Following the American Civil War and the abolition of slavery, the country was faced with the task of rebuilding the Southern states and integrating former slaves into society. The Republican Party, which supported civil rights for African Americans, held significant influence during this period.

Now, let's examine the different groups that you mentioned:

1. Scalawags: This term referred to Southern white individuals who were either Unionists during the war or who supported Republican policies during the Reconstruction era. While some scalawags genuinely believed in the principles of racial equality and the advancement of African Americans, others joined the Republican Party to gain political and economic benefits. Nonetheless, their support for the Democratic Party was limited.

2. African Americans: After being emancipated from slavery, African Americans gained the right to vote with the passage of the 15th Amendment in 1870. Many African Americans supported the Republican Party during Reconstruction because of its stance on civil rights and equal treatment. However, it is worth noting that not all African Americans supported the Democratic Party, as some were oppressed and intimidated by white supremacists who aligned with the Democratic Party.

3. Rich Landowners: While many wealthy landowners in the South initially opposed the Republican Party due to their opposition to the abolition of slavery, they gradually joined the Democratic Party. The wealthy elite in the South sought to regain and consolidate power, and they found alignment with the Democratic Party's conservative ideology and support for states' rights.

4. Carpetbaggers: The term "carpetbaggers" referred to Northern individuals who migrated to the South during the Reconstruction era, often with the intention of pursuing economic opportunities or participating in politics. While many carpetbaggers were indeed affiliated with the Republican Party, it's important to note that not all of them supported the Democrats. Some carpetbaggers supported the policies of the Republican Party, including civil rights for African Americans, and remained aligned with the Republican Party.

In summary, during the Reconstruction era, the groups of Americans in the South who primarily supported the Democratic Party included some scalawags, rich landowners seeking to regain power, and those white supremacists who oppressed African Americans. However, it is essential to remember that political affiliations during this period varied, and not all individuals within these groups unequivocally supported the Democratic Party.
