To fully understand how the Republican Party in the days of Fremont and Lincoln, evolved itself into a "different" ideology, a bit of its history needs to be revisited. The Republican Party had descended mainly from the Whig Party. These people were economic nationalists and were connected to a broad national society. This included merchants, farmers, shopkeepers and manufacturing interests. Its abolitionist wing was always small even in the Civil War days, but they were a very vocal minority. The Republican Party was not really changing in the 1870's. In that sense it was not discarding anything but the antislavery people who no longer had a major and moral goal: the elimination of slavery.
The Party was simply reverting to its roots which were basically involved with growing the US economic sectors of the American economy. With of course, not being concerned with the Southern economy.
