My county has databases of its 15,000 voters. I would like to put them on my IPAD and go door-to-door campaigning against a far -right candidate. WHat is the best way to get these lists on an IPAD and access them as I go round the different neighborhoods? I could put + or - , Needs a year sign, etc nothing too fancy. Perhaps look at the list by street or who voted in which primary. The county will have that on Excel-- I want to carry it around. I have IPAd 4 with 64k Which programs would be best? ANy other ideas on doing this?
