Although Conservatives are a legitimate branch of the GOP who have made many positive contributions, this wing of the party has allowed itself to be dominated by extremists and social moralists that marginalize Lincolnian principles. Doing so doesn't make them less Republican. It demonstrates that they have the honor, political courage, and intellectual honesty to put nation above party. The principles of Moderates are clear. They do not pick and choose among the opposing Liberal or Conservative ideologies to form their own.
Moderate lawmakers are consensus builders.
But then again the art of legislating is that of compromise, negotiation, and a recognition that other views have merit. This does not mean Moderates compromise core values, but rather they understand the complexities of passing intelligent legislation that benefits the greater good. They also engage in spirited debate among themselves which sometimes limits their strength as a coherent, national force. This passion for public policy discussion permits detractors to label them indecisive. Moderates sometimes forget that ideas alone don't win political battles.
