The number to hit: 270

The U.S. presidential election is a numbers game. No surprise there. But the numbers that matter are the electoral votes, not the popular vote. To win, Donald Trump or Hillary Clinton must have at least 270 electoral votes on Election Day. The total number of electoral votes — 538 — equals the number of senators and representatives for each state plus three electoral votes for Washington, D.C.
