How did the results of the congressional elections of 1986 hamper President Reagan in the final two years of his second term?

The 1986 congressional elections resulted in significant gains for the Democratic Party, which regained control of the Senate. This shift limited President Reagan's ability to pass his legislative agenda, as the newly empowered Democrats were more inclined to oppose his policies. Additionally, the divided government led to increased partisan conflict, making it more challenging for Reagan to negotiate and achieve bipartisan support for his initiatives in the final years of his presidency.
