A lifelong Democrat, Thomas A. Hendricks was the definition of a party man, voting the party line time and time, even if modern Democrats would be appalled at his voting record.
Indeed, his rise to power during the Reconstruction Era saw this Southern Democrat oppose all attempts to heal the rift created by slavery, including supporting Andrew Johnson after his impeachment and voting against the thirteenth, fourteenth and fifteenth Amendments.
And this didn’t with his election as Vice President, if anything, it only strengthened his resolve and gave him more power to execute his agenda.
