Final answer:
The conservative Republican Party has been strengthened at the expense of the more liberal Democratic Party due to factors such as economic policies, social issues, immigration laws, and redistricting.
Step-by-step explanation:
The strengthening of the conservative Republican Party at the expense of the more liberal Democratic Party can be attributed to various factors. One factor is the appeal of conservative economic policies, such as lower taxes and deregulation, which resonate with conservative voters. Another factor is the focus on social issues, such as opposition to abortion and support for traditional family values, which attracts conservative voters. Additionally, changes in immigration laws and redistricting have also played a role in shaping the political landscape in favor of the conservative Republican Party.
