Selection and Descriptions of Congressional Key Votes
Project Vote Smart provides easy access to Congressional voting records and maintains a collection of key votes grouped by issue. Key votes typically include the initial passage of legislation and final conference report votes versions (the compromised versions of bills passed in separate House and Senate version.). PVS uses a criteria to select key votes:
1. The vote should be helpful in portraying how a member of Congress stands on a particular issue
2. The vote should be clear for any person to understand
3. The vote has received national media attention
4. The vote was passed or defeated by a very close margin
5. Occasionally, a specific bill is consistently inquired about on the PVS Hotline; the vote is added to the web site
