The correct answer is B) members of the Electoral College were elected by popular vote, not their state legislatures.
The American election process changed by the election of 1828 in that members of the Electoral College were elected by popular vote, not their state legislatures.
This represented a moment in US politics when people's votes showed what parties they support.
In the US election of 1840, the Whig party candidate, William Henry Harrison, defeated Democrat Martin Van Beuren. However, a month later after Henry took the Presidential office, he died. Vicepresident John Tyler became the President. In this election, US citizens showed the preference they had when they decided to vote for a Whig candidate, instead of the traditional bipartisan candidates.
