Texas is usually a “safe” state for the Republican Party in presidential elections; California is usually a “safe” state for the Democratic Party.
Also, note that swing state refers to any state in the United States of America where there are similar levels of support for the candidates of the two major political parties (Democratic and Republican party), which typically determines whether or not they would be a winner.
