I emailed John Heyer a bunch of questions and this was his response:

Lessons Learned? 

Stick
to your guns. Say what you believe, speak about what you think is
important, and let those who feel the same way find you. Of course, if
we lose, I will try to unlearn these things.

Highlights? 

Seeing my posters all up and down Court Street and 13th Avenue is pretty cool.

Regrets? Mistakes? Gaffes? 

Things
got nasty between supporters of mine and supporters of Brad's in Boro
Park. We're friendly, and neither of us should have allowed things to
escalate to that degree. It's a disservice to the community, whoever
wins.

Did you get your message across? 

I
think so. My message all along was constituent services – it's what I
think this job is about, and it's what the voters all want to talk to
me about as I go door-to-door. For the Brooklyn Paper to endorse me as
the nuts-and-bolts guy in this race, after everything that's happened
in the campaign, I think is an indication that my point got across.

Your takeaway from all this? 

I'll follow Brad's lead and say it's a bit too early for that level of reflection.

What you know now that you didn't know then about the district? 

People stay up really late in Boro Park. It is a different time zone.

What you know now that you didn't know before about politics?

Again, we'll see on Wednesday morning.
