What do red states and blue states mean in America?

Red state and blue state refer to the trend of vote distribution in American elections in recent years.

Among them, * * * and the party are represented by red, and the state that tends to support the party for a long time is called "red state"; Blue is the representative color of the Democratic Party. Voters in the western coastal and northeastern coastal States tend to support the American Democratic Party. Therefore, these States have developed economies, large populations and "diversified" structures (more new immigrants); On the other hand, the southern coast and the central part tend to vote for the United States and the party, so they are called red states.
