Why is "Pat Buchanan 2000 presidential campaign" trending?

Wikipedia Overview

The 2000 presidential campaign of Pat Buchanan, conservative pundit and advisor to both President Richard Nixon and Ronald Reagan, was formally launched on March 2, 1999, as Buchanan announced his intention to seek the Republican Party nomination for the presidency of the United States in the 2000 presidential election. It marked Buchanan's third primary campaign for the presidency, following his bids in 1992 and 1996. Although he had not attained the nomination either time, he had been regarded as a consequential party figure. Early primary surveys found Buchanan polling in the single digits and following the publication of his book A Republic, Not an Empire, which generally advocated for noninterventionist and "America first" foreign policy, some within the Republican Party condemned Buchanan's foreign policy views. There began to be speculation that Buchanan would leave the Republican Party in favor of the Reform Party, a third party qualified for matching federal campaign funds.
