Oops, only counted the yes. Here’s all:
Sum politicals = 275
Sum races = 278
Sum sexes = 188
Generally, the "don't know" response is largest with the independent group, which is why it's important to track the changes of this group over time. Will they break for Trump or for the Democrats? If the "favorable/unfavorable" spread is greater than the "don't know," then that's good news for Trump.
That said, this Fox News sample has a very small independent sub-group compared to other polls., making the swing of the independent "don't knows" less impactful to the overall results.
The full set of numbers is in the link at the top of the thread.
