Normally when a leader is elected, they have some strong transits that power them through their term of office. Trump's first Presidency had Neptune squaring his Sun and Moon; Biden had Neptune opposite MC followed by Pluto square Moon and Uranus opposite Sun.
I am left scratching my head, however, at the astrology of this year's candidates. Trump will have Uranus aspecting his Angles, Kamala her MC. And that will be that. It will be over for both of them in a couple of years. What sort of Presidency will that be? There is no sustained or steady progress here. After a rocky Uranian start, they will be a lame-duck President for the final 2 years of their term.
If I had to hazard a guess as to who will win, I would say Harris, because Uranus will be active for slightly longer, and in sign.
Looking at the US Sibly Chart for the next 4 years, we see Neptune opposite MC followed by a Uranus Return. The last time Neptune was here was in 1860, the beginning of the Civil War. This, perhaps, tells us why Harris/Trump won't get much done: the present polarisation and division in Congress, and the culture wars in the wider culture, are likely to become more intense and to paralyse the country. This fits well with the divisive, Angular Uranus Return in 2027.
Harris will have transiting Pluto in Aquarius square her natal Mercury in Scorpio.
