I'm sitting at a hair salon with the radio playing and there have been 3 Harris ads so far, nothing from Trump.
I haven't seen any banner ads or streaming ads for him either.
I know this is all anecdotal, but seriously: Where are Trump's campaign ads? They seem absent from the normie space.
EDIT: this is in a battleground state where he definitely needs his ads playing.
Battleground state reporting in. For the past month, I have received pro-Trump political spam in the mail every single day that mail is delivered. No, I am not exaggerating about the volume. There are new pro-Trump billboards that went up around the county recently. I use uBlock origin and don't watch TV so I can't otherwise comment on digital advertising, but the Trump campaign has definitely been reaching out here on physical platforms.
For comparison, I have not received a single piece of pro-Harris mail. I did receive 2-3 generic "Vote Democrat" pieces of mail, but that was for everyone on the ballot, not Harris-specific. I also received multiple pro-RFK Jr. pieces of mail before he dropped out.
I am not registered with any party.
I have no idea what is going on with OP's situation, but it does not reflect my personal experience. I suspect the advertising dollars are very tightly targeted by ZIP or county.
