Sen. Mitt Romney (R-UT) announced he will not seek a second term as senator. Most commentators remember him as the man who lost a winnable election in 2012 against Barack Obama and for being the sole Republican senator to vote to convict President Donald Trump during his two impeachment trials.

However, Romney has another legacy, one that will not redound to his credit. One night, during a primary debate, he single-handedly delayed a return to the moon program by at least four years, a full presidential term.
