Ads may work, but the need for TV ads id lessening — the millennial voting block (along with plenty of others) isn’t watching much TV in real time — they’re typically watching via DVR or on-demand, if at all. DVR watchers skip the ads; on-demand is often not packaged with the original ads. Online advertising is a better value to reach these voters.
Also, as was already mentioned, less is more — the campaign needs to find the right balance to inform but not annoy the public.
Donald Trump is on Facebook, Twitter and TV everyday. Americans are so bombarded by advertisements that they don’t really believe them anyway. Of course and ad for Hillary is going to make Trump look bad and her like a non-criminal.
When voters hear Trump at the debates and realize that he makes sense and they actually agree with a lot of what he says, that will be much more important.
But I do want to see some Trump ads out there as well.
