That depends on how much time you have got to dedicate to campaigning. A lot of candidates will still be working during the campaign period, and will be trying to juggle family responsibilities as well – it’s a lot!
I think you need a blend of face-to-face contact with voters and virtual campaigning (answering emails, being active on social media, responding to media enquiries – activities which reach a broader audience, but with less of a human connection). If you don’t have a lot of time to spare, then door-knocking is probably not much of a realistic option, but you can still manage face-to-face contact by going along to hustings, or even by standing in a public place with a banner identifying you as a candidate, and talking to people as they pass by.
Be careful with social media – it can really draw you in, and you can find you’re spending a lot of time on there, but only actually talking to a small pool of people. Be reasonably strict with yourself about how much time you’re going to give to social media, and how much time to answering emails and other virtual campaign activities.
Where you don’t have control over the timing of an event (hustings or presentations, for example) do get those in your diary nice and early.
Aside from that, I think it helps to have a plan for how you’re going to spend your time during the week ahead. You probably don’t want to plan much more than a week at a time, because it’s a really intense period and you want to give yourself enough flexibility to respond as things change! A plan isn’t a promise – don’t beat yourself up if you don’t stick to schedule – but it helps you to think through how much time you want to give to different campaign activities, and to make sure you’re balancing your time sensibly.
