First, the Federalist/Whig tradition is America's genuine conservative political tradition (the Jeffersonian/Jacksonian tradition has always been radical).
Second, the Republican party was formed as a single-issue party and that issue was "anti-extensionism." Many of the early Radical Republicans were actually anti-bank and anti-tariff, etc. (Thaddeus Stevens held the same position on money that many of today's neo-Confederates do).
After the Civil War was over the party's initial founder, Alvan E. Bovay, even suggesting ending the party (since it had achieved its purpose) and creating a new single-issue party based on prohibition and temperance.
Don't tell me . . . neo-Confederate . . . right?
LOL. Completely backwards. The Jefferson/Jackson party was always the most popular party. The Whigs had to continually result to gimmicks and subterfuge to get elected since their position were mostly unpopular. What exactly is "conservative" about inflationism and corporate welfare?
Thaddeus Stevens held the same position on money that many of today's neo-Confederates do.
Sigh... the inevitable Lincoln idolator.
Thaddeus Stevens was not a Whig. He was the leader of the anti-Mason party, and a complete loon.
