With elections in May and then the referendum at the end of June, one of the main tasks of campaigners on all sides will be to maintain momentum.
All campaigns can suffer from quiet periods but this cannot be allowed this time around, especially on the EU referendum. There will have to be a steady stream of comments, reports, surveys and news to keep the interest high. If one campaign dips, that leaves space for the other to fill.
But there will also be activity on the doorstep, not just through the national media and social media. What is not yet clear is whether either of the EU campaigns have people prepared to go out and knock on doors to talk directly to the electorate. Especially following a potential set of elections in May, many activists may find it difficult to motivate themselves again. If that is the case, then the wider electorate could be even more apathetic.
Turnout could be crucial in the final analysis so the more active the campaign, the more able it is to engage directly with voters, the more likely that campaign is to win.
The starting gun has been fired on Britain's EU referendum campaign with 10 weeks to go before polling day.
