This is of course textbook Daily Mail politics.
First read the Daily Mail and pick a subject they're showing an interest in and you're department is in some way connected.
Then think of a way you can make whatever the subject was go away, get regulated, banned, become more popular etc.*
Thirdly make many pronouncements about how the dreadful or good* the current situation is and that you plan to address it.
*depending on topic.
Fourthly try and introduce legislation to produce the desired results despite how dumb it is, unlikely to work etc.
Wait for the votes to flood in on election day.
