Naturally, politicians are going to tailor their words and their reactions to their audience. If they are on your side, they will be enthusiastic, welcoming, supportive, critical of politicians on the other side and generous in their promises of assistance. They will also tend to remember other urgent appointments they have fairly soon after you enter their office. Mention mutual friends or acquaintances. Ease into your subject.
Few people fail to respond to friendliness.
But don t take a large delegation either. It s better to split up your lobbying efforts to make them more continuous. Three or four people in a politician s office is just about right. More than that becomes an audience. Take allies from your community groups or organizations, such as a church official.
