continuing polarization, with no candidate except Obama in 2008 winning by more than five percent of the popular vote and two — George W. Bush and Donald Trump — winning in the Electoral College while losing the popular vote. Both Clinton and Trump were impeached by a House controlled by the opposition party, but the impeachments did not appear to have long-term effects on their political standing. Critics of presidency's evolution The nation's Founding Fathers expected the Congress—which was the first branch of government described in the Constitution—to be the dominant branch of government; they did not expect a strong executive department. However, presidential power has shifted over time, which has resulted in claims that the modern presidency has become too powerful, unchecked, unbalanced, and "monarchist" in nature. In 2008 Professor Dana D. Nelson expressed belief that presidents over the previous thirty years worked towards "undivided presidential control of the executive branch and its agencies". She criticized proponents of the Unitary executive theory for expanding "the many existing uncheckable executive powers—such as executive orders, decrees, memorandums, proclamations, national security directives and legislative signing statements—that already allow presidents to enact a good deal of foreign and domestic policy without aid, interference or consent from Congress". Bill Wilson, board member of Americans for Limited Government, opined that the expanded presidency was "the greatest threat ever to individual freedom and democratic rule".

Nevertheless, the modern presidency exerts significant power over legislation, both due to constitutional provisions and historical developments over time. Signing and vetoing bills The president's most significant legislative power derives from the Presentment Clause, which gives the president the power to veto any bill passed by Congress. While Congress can override a presidential veto, it requires a two-thirds vote of both houses, which is usually very difficult to achieve except for widely supported bipartisan legislation. The framers of the Constitution feared that Congress would seek to increase its power and enable a "tyranny of the majority," so giving the indirectly elected president a veto was viewed as an important check on the legislative power. While George Washington believed the veto should only be used in cases where a bill was unconstitutional, it is now
