This show is pro Trump

Did you miss the parts that described how the fictional Reagan administration militarized the USA's presence on the moon which then lead to increased tensions that were only resolved by the independent actions of astronauts Baldwin and Poole?

He also allowed the coverup of the attempted production of weapons grade plutonium at Jamestown.

This frames him as the same kind of incompetent person he was during the Iran-Contra Affair.

How does this reflect on Trump at all? Trump is in no way a Reagan or Eisenhower style Republican.

Trump is awesome!

I don't think so, Reagan himself was mocked by Molly Cobb (season 2 IIRC). Also the entire show is based on gender equality boosting from the very beginning of the alternate history.

Last, but not least, they made Ellen Wilson a republican, when she should be obviously a democrat. Also they made her a lesbian, which most if not all reps would find insulting.

I don't think it is pro-Trump, I think they were trying to not be seen as "Liberal Hollywood", and by the way Gore beats out Bush, which is a nice touch and would have saved the world a lot of misery had it happened in reality.
