It hasn't been 'essential' since the 1860s, when the question was pretty much settled in favor of -the- United States, versus -these- United States.
Or, in reality, allows a collection of four to five random states decide who gets to be President regardless of whether or not said individual has a popular mandate.The constitution enumerates what powers the federal government has. Anything not granted to the federal government, the states are free to decide for themselves. That's the entire basis on how this country is setup. It's trending toward the federal becoming more powerful than the states, which is why things like the electoral college is important.
In order to better understand it, you should regard the states as their own sovereign countries. The job of the federal government is to essentially keep the interests of all the states in mind instead of letting one state grow too powerful and dictate to all the others. And that's why the Electoral College is also important - it keeps one state or a collection of large states from putting into power the chief executive, bypassing what all the other states may think.
Here's why the popular vote is a big deal.And for all of you that think the popular vote is a big deal, keep this in mind -
The House of Representatives is where the publics direct popular votes count the most. Control of the House is important, as the Republicans demonstrated during both of Obama's terms.
In a democratic system, the concept of popular mandate is pretty important owing to the fundamental assumption that the government derives its authority from the general will; by implication, a government that is put into place lacking a popular mandate has no grounds for its authority. Moreover, as the stability of the social order is contingent on people being invested in its wellbeing then an order in which people think they have no stake is fundamentally anemic.
Gerrymandering. This has been known for some time.Despite Hilary Clinton winning the popular vote, the Republicans still retain control of the House. How is this possible?
It's yet to be established as to why this is a bad thing since the 'small number of population centers' contain -most- of the entire nation.Well, it's simple - it means the majority of Clinton voters were concentrated. That usually means major population centers, which means that anyone saying the popular vote means Clinton should be president, means that they're in favor of a small number of population centers largely directing the fate of the entire nation.
Why do we care?This is exactly what the founding fathers did not want.
You mean like how elections are currently decided by a select few states that don't lean very heavily towards either party? Or how the present government is in effect a minority government?If we ever devolve to the point where important decisions are made only by a select few areas of the country as a de facto standard of government, the road to a second civil war will begin.
