Because the way voting works in the US is based on assumptions from the days when getting all the votes together to tally them would have been a logistical nightmare. Instead of counting everyone’s vote individually, the map is divided into regions. Each region tallies up their votes, and then one single vote is counted for that entire region based on the majority vote from that region. Those regional votes are tallied, and the majority winner of the regions gets the win. By drawing the regions correctly (a process called gerrymandering), you can put the majority of one party’s voters into a small handful of regions, so all of them only count as a handful of regional votes while making sure the rest of the regions are drawn to give the other party a 51%+ majority. As a result, it’s possible to have a candidate that would garner less than 50% of the individual votes win a landslide of over 75% of the regional votes.
