It does seem strange that the OP hasn't been canvassed or even leafleted at all. I wonder if it is possible that most parties are assuming that your estate is 'owned' by the Shinners or the Greens perhaps, and have decided to prioritise their work on more fertile grounds.
We live a small estate (32 houses) which seem to attract little attention for campaign planners. While canvassing my own estate with Labour, a couple of people noted that they hadn't been canvassed yet for this election. We get a fair bit of bumpf through the door. If you do want to hear from Labour, send me your name/address by PM and I'll get someone round to you.
I even registered for the Fine Gael and Fianna Fail ezine so if anyone checks this list against the register they would know I am interested in politics.
It would be very difficult to do this cross referencing. Did you give a full address when registering for the e-zine? If not, it would be impossible to link you to the register. If yes, it would still be difficult to do this cross-reference, given the variety of names (Pat/Paddy/Patrick) and the possibility of multiple similar names at the same address. It would also need party Head Office to be sending out lists to every branch in the country on a regular basis, and the volunteers at branch level to be diligent in using this data. And finally, unless they indicated in advance that they were going to use the data for canvass purposes, it would be illegal!
They go around with an electoral register with their own comments on each household based on local and historical knowledge. Someone local probably said- don't bother with that guy on the end there, he's a wiseass and will only bend your ear about nurses/berties money etc before voting for FF anyway.
It is very, very difficult to coordinate comments on an electoral register. If you have a smallish team of say 6 canvassers, you would have to
1) Copy your existing register 6 times
2) Step through the register at each house (adding about 30-60 seconds to each house)
3) Collate the feedback from 6 canvassers onto one master copy
4) Transfer the comments from that master copy each year when the register is updated
It's just not that easy.
