FEDERALISM / FEDERAL FORM OF GOVERNMENT IN THE UNITED STATES = two governments--national and state--sharing power and/or competing for power.
National Highway Traffic Safety Administration has mandated Federal Motor Vehicle Safety Standards (FMVSS) and Regulations under the Motor Vehicle Safety Code, which manufacturers of motor vehicle and equipment items must conform and comply with. These regulations state minimum safety performance requirements for motor vehicle types and components. (http://mature.idrivesafely.com/course/outputContentHtml.pl?WST=1277859847
Below is an excerpt revealing differences among Federalists and Republicans who served in George Washington's Cabinet
Hamilton (Federalist) and Jefferson (Democratic-Republican, called "Republican") in Washington's Cabinet
ferson arrived in Virginia in November 1789 to find George Washington waiting for him with news that Washington had been elected the first president of the United States of America, and that he was appointing Jefferson as his secretary of state. Besides Jefferson, Washington's most trusted advisor was Treasury Secretary Alexander Hamilton. A dozen years younger than Jefferson, Hamilton was a New Yorker and war hero who, unlike Jefferson and Washington, had risen from humble beginnings.
Incredibly rancorous partisan battles emerged to divide the new American government during Washington's presidency. On one side, the Federalists, led by Hamilton, advocated for a strong national government, broad interpretation of the constitution and neutrality in European affairs. On the other side, the Republicans, led by Jefferson, promoted the supremacy of state governments, a strict constructionist interpretation of the constitution and support for the French revolution.
Washington's two most trusted advisors thus provided nearly opposite advice on the most pressing issues of the day: the creation of a national bank, the appointment of federal judges and the official posture toward France. On January 5, 1794, frustrated by the endless conflicts, Jefferson resigned as secretary of state, once again abandoning politics in favor of his family and farm at Monticello.
At home, Jefferson spent his time farming, managing his finances and making improvements to the estate. It was also at this time that Jefferson most likely had an affair with a slave named Sally Hemings, who was [the half-sister of Jefferson's wife, Martha, who had died in 1782]. Sally's mother, Betty Hemings, was a slave owned by Jefferson's father-in-law, John Wayles, who was the father of Betty's daughter Sally. While there is no definitive proof that Thomas Jefferson had children with Sally Hemings, the circumstantial evidence is all but conclusive: Jefferson was with Sally (either in France or at Monticello) nine months before the birth of all six of her children.
Furthermore, historical records corroborate the stories passed down orally through the Hemings family. Most compelling is recently produced DNA evidence showing that some male member of the Jefferson family fathered Hemings' children, and that it was not Samuel or Peter Carr, the only two of Jefferson's male relatives in the vicinity at the relevant times. It is therefore overwhelmingly likely, if not absolutely certain, that Thomas Jefferson fathered Sally Hemings' children.
In 1797, despite Jefferson's public ambivalence and previous claims that he was through with politics, the Republicans selected Jefferson as their candidate to succeed Washington as president. In those days, candidates did not campaign for office openly, so Jefferson did little more than remain at home on the way to finishing a close second to then-Vice President John Adams in the electoral college, which, by the rules of the time, made Jefferson the new vice president. Besides presiding over the Senate, the vice president had essentially no substantive role in government. The long friendship between Adams and Jefferson had cooled due to political differences (Adams was a Federalist), and Adams did not consult his vice president on any important decisions.
