After Baker v. Carr (1962) there was a power shift in both national and state legislatures. Explain. How did the Lyndon Johnson Administration benefit from that shift?

Baker v. Carr (1962) dealt with the issue of apportion of legislative units. It led to an increase in legislative representation for the populous urban districts.

Step-by-step explanation

The court asserted that every individual had to be given equal consideration in legislative matters. As a result several states had to carry out legislative redistricting. In the new redistricting population had to be major consideration. This led to a power shift the legislature. The regions with more population such as urban areas experienced greater representation. More legislators were from the populous urban areas meaning that the issues of the people in the areas with small populations had little power in both state and federal legislatures. 

The shift of balance was of great benefit to the Lyndon Johnson administration. In his tenure as president he was able to attract support of the legislators to pass important policies. Most of the new legislators were from areas that had been previously underrepresented and his agenda such the war on poverty and Medicare and Medicaid resonated with the people (History, 2020).
