What is a key outcome of realignment in political parties?

A key outcome of realignment in political parties is a shift in popular support and party strength. Realignment occurs when significant changes in the political landscape lead to a dramatic alteration in the preferences and voting behaviors of large segments of the electorate. This can happen due to changes in demographics, sociopolitical issues, or major events that reshape public opinion.

During realignment periods, voters may leave one party to support another, and this shift can result in a new dominant party or coalition emerging, fundamentally altering the balance of power in the political system. This is often evidenced by significant electoral wins for a party that previously had less influence, leading to changes in policy priorities and governance.

In contrast, a decrease in voter participation is generally not a feature of realignment; instead, realignment can energize different voter bases. Stability in party coalitions might be expected during times of political agreement, but realignment often brings instability as parties redefine their platforms and coalitions. Increased polarization tends to be a consequence of such shifts in certain contexts but is not the sole outcome of realignment itself. Thus, the most direct and accurate reflection of realignment is the shift in popular support and party strength.
