Politicians want support but they're not helpful in the end!?

I've worked closely with a few politicians over the past decade as a resident and a reporter for my local paper. They attend block parties, senior center events and of course want the publicity!!!!

I recently began coordinating an event to benefit a cancer which took my dad's life - and I'm getting a lot of great volunteers and even companies are sponsoring the event and giving away stuff.

Of course, or strangely - when I asked the few politicians who were always sooo nice to me to help me get the word out or help me obtain rescources, they've done NOTHING!

I'm NOT asking for their money or donations, I was hoping they'd actually spread the word and work in collaboration with me since I always gave them positive press and my event is for a good cause.

Why bother voting for politicians who limit their "support" to select events. Even if they shared my event on social media once or twice, I feel like I expected more involvement and help from those I voted for.

Should I be persistent and ask them to help more or cut it as loss to the event even though they wanted their names attached as "sponsors".
