Elections are intended to be a product of the will of "we, the people."
We are a sovereign nation.
We have a democratic system of government.
Under that system, the American people choose their government.
From writing the Constitution straight thru the 1790s, people worried re: England or France swaying American politics their way.
They also recognized that intense partisanship made such behavior even more likely.
You'll see scores of angst-ridden fears re: a foreign nation manipulating the US into promoting foreign interests and not its own.
"If...Suffrage can be obtained by foreign nations by Flattery or Menaces, by fraud or Violence, by terror Intrigue or Venality, the Government may not be the choice of the American People, but of foreign nations...."
"It may be foreign nations who govern Us, and not We the People who govern ourselves."
It's a valid fear that's worth remembering.
We the People govern ourselves.
