This shows that even with her high budget nearly doubling Trump’s for advertisements and media alone were simply not enough to win the election.
does this sentence sound okay? i think it needs be better sounding for some reason
The problem you're sensing is that there is no subject for the main verb "were." Also "This shows that" is rather clunky. If you change it to "Thus," it'll be smoother.
Thus, even with her high budget nearly doubling Trump’s for advertisements and media alone, ______ were simply not enough to win the election.
What will you put in the blank?
