1. A viable strategy: retain Labour’s 2015 vote and add disaffected Labour supporters and young people who didn’t vote in ’15 or who voted for Green or UKIP as a protest.
2. A simple narrative: we’re willing to make radical decisions to improve the lot of normal people.
3. An authentic leader: consistently on the side of the marginalised.
4. Motivating policy offer: more money for the NHS, schools and pensioners, scrap university fees, create a national investment bank and, crucially, remain in the European single market.
5. A clear enemy: high earners and multinational corporations.
6. Kept journalists busy: public events, relevant celebrity endorsements, bold statements (foreign policy speech post-Manchester), gave clear answers to questions and attended the debate.
7. A humble approach to battlegrounds: left Labour candidates in marginal seats alone to try and win over wavering voters whilst visiting strongholds to generate a sense of momentum in national news coverage.
UPDATE: I’ve since written a long-hand version of this for The Drum, which you can read here.
