Final answer:
Since 1968, the Democratic Party has won 6 out of the 11 presidential elections up to 2008, reflecting the changing dynamics of the Fifth and Sixth Party Systems in the United States.
Step-by-step explanation:
From -1968-Present, the dominant party in the United States' presidential elections has changed over time. During the Fifth Party System, Democrats were largely dominant, controlling the presidency and winning a considerable number of elections, mostly due to the New Deal coalition. However, the Sixth Party System has been characterized by a lack of dominant control by a single party. Instead, there has been an ongoing realignment, with shifts in the electorate.
Specifically, since 1968 through the present, the Democratic Party has won 6 out of 11 presidential elections if we count from 1968 to 2008. The realignment has included southern White people and many northern members of the working class beginning to vote for Republicans, while Democrats have attracted Latino and Asian immigrants.
