Seven O'clock vaguely sympathetic to Trump?

I'd be surprised. I don't believe Ed would say "lost eloquence" since I don't believe there was a single period of time where Trump could have been considered eloquent by anyone, let alone Ed. Trump riffs, and speaks with a limited vocabulary and favors monosyllabic words. There's nothing approximating eloquence about that guy.

The song is most definitely aimed at Trump. 

Sitting Bull and Crazy Horse forged the North and West
Then there's Sitting Bullshit as our sitting president

It's not being sympathetic towards him, it's quite the opposite.

Sure, those lines clearly are derisive towards Trump.  But the lyrics I am talking about immediately follow those and strike a very different tone to me.

To me, it seems that the lyrics after are still shots at him and his Twitter tirades. 

Thought Soon Forget was about him when I heard it. A lot of people are disappointed that outcome didn't happen. 7OC could be an attempt at empathising even though he can't stand the orange one.

it's definitely about Trump.

Luminous can mean harsh.

Eloquence can mean persuasive speaking.

Engine room fires are bad on ships. His ship is in trouble (presidency).

Relief coming soon refers to his cronies, help bail him out like they've always done.

Don't worry - it's all bad and sarcastic.

This is exactly how I've interpreted this verse, although no idea if it's correct

Or at least the verse is speaking about the narrator of the song. 

I don't interpret this verse as having to do with Trump at all. I'm not sure who it is; it could be the narrator, or Ed, or anyone else. I interpret the "fire in the engine room" as a good thing, ie, such as when a very competitive athlete is said to have "fire in their belly." In other words, times may be bad (because of Trump) but we still have fight in us. And we can see relief on the way, as edocon said, in the form of the next election, or the belief that we have to end up on the right side of history.

I view the whole song being about the US position and the position of the presidency. 

I view the first 2 verses being about the despodency ed feels with where the US is and the role the president has played in that, the message from down under where dreams are still being made shows that this feeling he is feeling is about the US and his lack of being able to dream for the future.

The next 3 verses are about getting close to having it right with the last president and having that all taken away, the freedom part in verse 3 to me is about voting and how that process gave hope for the country and then took it away again when Trump was voted in. He now feels he is swimming against the tide to get back what he wants for the country. The butterfly in my opinion is the US again and what makes the country beautiful and amazing has been stripped away.

Verse 6 is a full on attack of trump and blaming him for all of the problems above but I think in verse 7 ed starts to talk about the position of the the presidency and the US again. The relief that is coming soon is the possibility that the position and the country will be saved by someone else in the role.

The last 2 verses are about putting in the preparation and work for that change to happen, the carve a path for rivers to reign to me is about creating an opportunitity for ideas to be heard and to overcome the misinformation he believes is out there. The hangman is the American people that Ed hopes will end this but to achieve it there is still much to be done.

That is just my take on it and I'm an Aussie so may be way off when seeing the political side of the song.
