So, sometime between the 1860s and 1936, the (Democratic) party of small government became the party of big government, and the (Republican) party of big government became rhetorically committed to curbing federal power.

The term Democratic-Republican is used especially by modern political scientists for the first Republican Party (as opposed to the modern Republican Party founded in 1854). It is also known as the Jeffersonian Republicans.
