1) My "scut work" is done. I don't know what your objection is because you're way too cool to tell me. Apparently, your preferred method of discourse is to throw out vague statements and then sit back and feel smug.
2) The exact timeline of the ascendance of the modern Republicans and Democrats is almost unrelated to the main point of my statement. If you can't be bothered to make your counter-point, then I can't be bothered to refute it.
As any educated person KNOWS, the two party system came into being after the Jefferson presidency and was in FULL swing/bloom by
1828.
Ergo, your supposed scut work looks to have been nonexistent. Instead, you demand to be spoon fed factual history, which for some reason or other, you aren't cognizant of.
