Add McCain, George H.W. Bush, George W. Bush to that list ..
Indeed !
The Republican party was born in the first place because an already existing party, the Whigs, nominally the “conservatives” of their day (as opposed to Jacksonian Democrats), could not, or would not, take a moral stance in regards to the festering problem of slavery in the US at the time, with a balanced number of states that authorized the keeping of slaves, and those states in which it was prohibited. Not everybody in the “slave states” kept slaves, but everybody in the “free states” could not keep slaves at all. Serious problems arose, should a slave escape from his master and make his way to a “free” state. Keep him free, or send him back? Made for some interesting Supreme Court decisions, and just one more example of why the law is never “settled”.
Romney too
