Brief Explanations:

In the early 1990s, the poor economic conditions led to a political shift. Voters were dissatisfied with the status - quo. The Republican Party capitalized on this discontent. In 1994, there was a significant electoral change. The Republican Party won a majority in Congress, which meant new congressional leadership (as the previous leadership was likely from the Democratic Party which was in power before in many cases). Republican voter participation did not decline; in fact, it increased as they were more motivated. Democratic voter participation did not increase in a way that would counter the Republican gains. Congress was not unable to create new policies; rather, the composition of Congress changed.

Answer:

new congressional leadership was elected in 1994.
