What political risk did mondale take in 1984 that may have cost him the election?

In the 1984 presidential election, Walter Mondale took a significant political risk by openly proposing to raise taxes to address the federal budget deficit and social programs. This candid approach, while aimed at transparency, alienated many voters who were concerned about tax increases during a time of economic recovery. Additionally, his decision to select New Jersey Governor Thomas Kean as his running mate was seen as a move that lacked the appeal to moderate and conservative voters, further diminishing his chances against incumbent Ronald Reagan. Ultimately, these risks contributed to Mondale's substantial electoral defeat.
