Let's see. Jefferson railed against government debt, lead the Anti-Federalists, insisted on government being very small and limited. "That government governs best that governs least." Jefferson would be welcomed.
Washington was a man of profound character. Upright and moral baring, gentlemanly manners, a successful business man, successful soldier, leader, self educated. He insisted on a reliance on Providence. He was a churched man and prayed regularly. He insisted on duty, selfless service to his country and was generous with himself and his wealth. He did not insist that others be compelled toward generosity by an over reaching state.
Lincoln was self made, self educated and he too, insisted on a reliance upon the divine. He spoke often of providence. Lincoln also understood the value and nature of private property rights. He was also a man of profound character.
All three sound like the kind of men that conservatives would gladly welcome. The only liberal(the current meaning) position taken by any of them was Jefferson's support of the French Revolution.
