Your Vote for Trump did not put him in the White House
The Electoral College put Donald J Trump in the White House

Usually, political parties nominate electors at their state conventions. Sometimes that process occurs by a vote of the party's central committee. The electors are usually state-elected officials, party leaders, or people with a strong affiliation with the Presidential candidates.

The Electoral College consists of 538 electors. A majority of 270 electoral votes is required to elect the President. Your state's entitled allotment of electors equals the number of members in its Congressional delegation: one for each member in the House of Representatives plus two for your Senators.

The Electoral College vote on December 19, 2016, seven electors voted against their pledged candidates: two against Trump and five against Clinton. A further three electors attempted to vote against Clinton but were replaced or forced to vote again. Ultimately, Trump received 304 electoral votes and Clinton garnered 227, while Colin Powell won three, and John Kasich, Ron Paul, Bernie Sanders, and Faith Spotted Eagle each received one.

In 2016 there were 200,000,000 eligible voters

Would these votes have changed the outcome?

More Americans voted for Hillary Clinton than any other losing presidential candidate in US history. The Democrat outpaced President-elect Donald Trump by almost 2.9 million votes, with 65,844,954 (48.2%) to his 62,979,879 (46.1%), according to revised and certified final election results from all 50 states and the District of Columbia.

My biggest problem with Electoral College is that it encourages candidates to campaign in swing states and ignores the rest of the country.
