70% cannot steal an election. If 70% vote for said person, be it a Dem, Repug, or even Green party (Yes, there are more than two or three parties in the U.S.) it is called a majority
or the popular vote and the person they voted for ideally wins the election. However, while Hillary won the popular vote, the Electoral College (paid off probably, but Russia did meddle in our last election) decided to vote for the dotard, instead of listening to the people or popular vote, thereby placing the dotard in office against the majority’s desire. So there is no way 70% of the nation can steal an election, but the E.C. can do what they want, even accept payoffs, even though that’s not legal and/or be influenced by a foreign government, which also is not legal. Basically, the people are at the mercy of the E.C. when it comes to an election.
