What did Ronald Reagan promise to do during his presidential campaign in 1980?

On May 20, 1980, after the Michigan and Oregon primaries, Ronald Reagan secured enough delegates to clinch the nomination for the Republican Party. His opponent in the general election, incumbent President Jimmy Carter, passed the delegate threshold to become the presumptive nominee of his party on June 3.

His plans were for a huge shrink in big government, a balanced budget, and to lower taxes and increase revenue.
