How America Elects Its President（ZT）
After each party determines its presidential nominee, the candidates strategically choose a running mate. The team then aggressively campaign in preparation finale in early November.
On general election day, registered voters go to their local polling center to make their choice for the president. Although the vote is crucial, the president will technically be determined by a system called Electoral College.
The Electoral College is made of representatives or electors, that are allocated based on the voting results in each state. States with big populations have more electors. States have smaller populations have fewer.
To win the presidency, a candidate must win the majority, or 270 the electors. The electors then cast their votes about a month later. But the new president doesn't offically take office until the inauguration ceremony in late January.
