Threats or open antagonism are seldom, if ever, helpful and often counterproductive. Be sure to provide legislators with the arguments in support of the pro-life position, even if you think certain legislators are only interested in the personal ramifications of their position, they need to know why the legislation is needed. If the legislator asks a question to which you don't know the answer, don't guess. Tell him or her that you will provide the information later, and do so. If you give a legislator misinformation, it can erode your credibility and that of other pro-life individuals.
Many legislators like to keep their options open.
Don't mistake vague expressions of sympathy for real commitments. You will not always obtain a firm answer, but you should try. We must also learn to deal with excuses clever politicians devise for why they aren't pro-life. The best way to deal with this is to listen patiently to complaints and then make it clear you believe that there is not an acceptable reason for refusing to support the pro-life cause if one is sincere about wanting to save lives. As soon as possible after the meeting, write up a summary of what was said.
