1) In July 2020, a reporter said that something surprising was happening in Texas - a new voting intention poll showed a statistical tie between republican candidate Donal Trump and Democratic candidate Joe Biden. This was surprising because, in Texas, democratic presidential candidates had always lost since 1976.

However, the poll results indeed showed a larger proportion of Trump supporters (48%) than Biden supporters (46%).

Why is that called a "statistical tie"? Use as much vocabulary as possible.
