Wouldn’t read too much into. NY is also absent from the list, and I’m seeing Trump ads here on LI. And they’re paid for by Trump, not some donor or PAC.
I just started seeing Trump ads on Lifetime and LMN here in NYC...Hillary has had them for-evah.
Trump is also on the air in Seattle - the Trump campaign, not a PAC.
So am I, but they could be national cable ads. Even so I cannot recall ever seeing a McCain or Romney ad. In those days only ads I saw were for Congress and State legislature. Trump is doing things differently.
