Unless something unexpected happens, there will be no Republican Party in 2016.
Based on the following excerpt from Thomas Jefferson's writings, in his time the rich uniquely paid the taxes to keep the federal government running.
"The rich alone use imported articles, and on these alone the whole taxes of the General Government are levied (emphasis added). Our revenues liberated by the discharge of the public debt, and its surplus applied to canals, roads, schools, etc., the farmer will see his government supported, his children educated, and the face of his country made a paradise by the contributions of the rich alone, without his being called on to spend a cent from his earnings." --Thomas Jefferson to Thaddeus Kosciusko, 1811.
But also note that most of the delegates to the Constitution Convention were wealthy, George Washington the Bill Gates of his time. So not only did the delegates draft the Constitution, but by signing their names to it it they were essentially committing themselves, their rich friends, and other rich citizens, to uniquely bear the burden of paying for the federal government to operate.
On the other hand, and this is a major point, regardless that the rich were paying for the federal government to operate, Justice John Marshall had officially clarified that Congress is prohibited from laying taxes in the name of state power issues, essentially any issue which Congress cannot justify under the Constitution's Section 8 of Article I.
"Congress is not empowered to tax for those purposes which are within the exclusive province of the States." --Justice John Marshall, Gibbons v. Ogden, 1824.
In fact, note that the only federal government service that citizens should be regularly paying for, as evidenced by Clause 7 of Section 8 of Article I, is postal services. In other words, based on Justice Marshall's clarification of Congress's limited power to lay taxes, it is the individual states, not the federal government, who should be taxing and spending for government services like retirement, healthcare and public schools.
As a side note to Jefferson's statement about the rich uniquely paying taxes, note that the US postal service did not start selling postage stamps until the late 1840s.
The bottom line is that the problems that we are now experiencing with unconstitutionally big federal government are a consequence of parents failing to make sure that their children are being taught the Founding States' division of federal and state government powers evidenced by the Constitution's Section 8 of Article I, Article V and the 10th Amendment. And many times I think that constitutionally indifferent voters can sleep in the bed of constitutionally unauthorized federal taxes, federal taxes which Congress cannot justify under Section 8 of Article I, that they have made for themselves.
