Final answer:
The balance of power between the two national parties, the Democratic Party and the Republican Party, can vary at the state and congressional levels. It depends on factors such as the political ideologies of the voters, demographics, and historical voting patterns.
Step-by-step explanation:
The two national parties, the Democratic Party and the Republican Party, are not always balanced at the state and congressional levels. The balance of power between the parties can vary depending on the state and the district. In some states or districts, one party may have a majority, while in others, the balance may be more even or even split between the two parties.
For example, as of early February 2021, thirty states had Republican majorities in the state house and senate, while in eighteen states Democratic majorities were the norm. In only one state, Minnesota, party control was split so that the Democratic Party maintained control of one house while the Republican Party maintained control of the other.
Overall, the balance of power between the two national parties at the state and congressional levels is influenced by various factors including the political ideologies of the voters, demographic factors, and historical voting patterns.
