"if such number be a majority of the whole number of electors appointed;"

Currently there are 535 electors. 435 electors representing the total of congressional districts, and 100 electors representing the total number of US senators. 270 is the majority of electors.

Actually it’s 538 (3 for the District of Columbia), thus 270 is majority (269 would be a tie).

How many ran for POTUS? Two?

Does anyone think that the electors will throw out the vote from their respective states in favor of another nominee?

There are actually 538 electors. The 23rd amendment provides for Washington, DC, to have the same number of electors it would have if it were a state (but not more than the number assigned to the least populous actual state).

Long story short, since the 1964 presidential election, D.C. has had three electors.
