It's the one thing everyone everywhere can agree on. Surprised we've not had a presidential campaign around this issue.
Except that everyone everywhere does not agree on it. Keep in mind it was hugely popular when instituted, and the only people in modern times who've experienced it any other way (and therefore can weigh the alternatives with anything other than grass-is-greener thoughts) are those who've lived in Arizona or Hawaii (at least in the U.S.). I've experienced both (having lived in the former state), and I think DST makes more sense in some places (cold winters, disparate daylight times around the solstices) and less sense in others (hot summers and little change in daylight).
Which time? 1918, 1942, 1966, 1973?

The movie industry hated it, drive-in theaters couldn't play movies until 9PM during the longest summer days. Dairy farmers hated it, they already got up well before sunrise to milk but with the time change they had to get up an hour earlier so that they could get their milk onto the trains in time. More than a few people opposed it because it wasn't "God's time" or it was "unnatural". Odd, since standard time wasn't even law in the US until the 1918 Standard Time Act which included a DST time change... although that was removed in 1919.
Like a lot of issues, public opinion was largely split between rural and urban populations.
I think the reality is that we haven't been able to agree to any one method of keeping time since the railroad system and other forms of fast travel brought on the need for standardized time. Before that most clocks weren't synchronized very well, people were just a lot more flexible.
