A few years ago, the Senate approved a permanent move to DST by voice vote, but it never moved in the House. The bill was sponsored by the FL delegation, which as the eastern most southern state and a state that lives and dies off beach tourism, benefits the most from permanent DST. The problem is large swaths of the nation wouldn't see sunrises until well after 8 and sometimes 9 in the morning. WHich is why virtually every scientist recommends Standard, not DST as the year around time. While it's fun to have sunlight late in the evening, from a practical perspective as humans that evolved to wake with the sun and sleep with the night, we need more morning light, not less. It's why your dog is also so miserable: they have evolved to rise and sleep with us and it's very hard on them.
Fun fact: in 2005, Congress extended DST by 4 weeks. For the last two ish decades it's started 3 weeks earlier in the spring and a week later in the fall. That's part of the reason it feels so damn severe for most of us: The diurnal shock is much more aggressive than it used to be, when it was mostly about getting an extra hour at the bar in the fall.
