The 'Road to 270' in US presidential elections refers to the course a candidate must take to secure at least 270 electoral votes, the minimum number required to win the presidency.
The US uses an Electoral College system, where each state is allocated a certain number of electoral votes based on its population. There are a total of 538 electoral votes, so a candidate needs a majority—270 votes—to win.
The Road to 270 is important because winning the presidency is not determined by the national popular vote but by obtaining a majority of electoral votes. If a candidate fails to reach 270, the election is decided by the House of Representatives. Therefore, candidates must carefully plan their campaigns to focus on key states that can make or break their path to 270 votes.
