The 26th Amendment replaced the electoral college with a two round popular vote for President, imitating the system used in France. The amendment was filibustered by Southern Senators but Nixon twisted the arms of enough Republican Senators to make sure it passed.
However, the 1968 election result had been a mess where Nixon won a narrow popular vote plurality and Humphrey won a narrow electoral vote plurality. Nixon personally did not want to be in a position where George Wallace would play kingmaker again. Flip just a few close Humphrey states and Nixon probably gets an electoral vote majority and would not be as interested in backing the amendment. This would make a good POD for the USA to keep the electoral college system.
What would change? While there have been less than half a dozen subsequent elections that had to go to a second round, I imagine keeping the Electoral College would change the campaigns themselves considerably and also affect the nomination process.
