The Republican Party was formed to end slavery:

I am aware of that. But when they got into power, they didn't try to end it through legal means, such as a constitutional amendment.

As with most lying politicians, not only did they make no effort to get rid of slavery legally, they actually voted on a constitutional amendment to make slavery permanent. It's called the "Corwin Amendment."

Republican Abraham Lincoln was elected President....

And he urged the states to pass the permanent slavery amendment known as the "Corwin Amendment."

So with all of them working to make slavery permanently legal, how anti-slavery could they be?

LOL! Funny! The Southern states LEFT BEFORE THE FIRST REPUBLICAN WHO “GOT INTO POWER” could even act.

I wish you knew more about the Civil War, so you could comment from a more defensible position.
