Just speculation at this point but.....

The Guardian made a good point that about the first female president probably needing to be a Republican

Of course, if Ivanka does run for president, it will likely be on a Republican ticket and she will have to abandon her current pretence at mild progressiveness. Just look at the UK: there is a reason the only two female prime ministers we have had have both been Tories. Electing a woman who is also liberal as leader seems to be far too much for the British establishment to handle.

In the more religious, less tolerant US, it is even more of a challenge. Hillary Clinton may have won the popular vote in 2016, but the levels of misogyny directed against her made it clear that the US establishment still finds it near-impossible to stomach the idea of a female head of state. And certainly not one who is a Democrat.
