EDIT: Tried tightening question to be less broad.
In the post Civil War era, I see the Republican Party and Democratic Party basically retreading the old questions of early republic political economy after the war. I see basically the old agararian, limited government party (Democratic/Jacksonian) vs. the pro industry, pro big business, expanded government controls party (Whig/Republican) but the platforms become pretty unclear, and you could say not really based on ideology as we accumulated more distance from the Civil War.
I see this model being kind of thrown into a loop when Teddy Roosevelt becomes president, though. He seems anything but advocating for an agrarian state, but he actively tries to curb the power of the monopolies and big business. Then Woodrow Wilson becomes a president and as a Democrat, he helps passes measures such as establishing an income tax and a national banking system that seem a little antithetical to the traditional tenets of old school Democrats. These two presidencies seem to be the output of a growing progressive current that wanted reform in American society and yet I'm not sure if if there's a conenction between here and the modern political parties in America today. My question is, what implications, if any, did these progressive presidencies have on the idealogies of the seemingly non idealogical Democrat and Republican parties at the time?
