Once the boy wonder of Maryland politics, Mr. Cardin has 40 years of legislative experience to his credit, including a stint as one of the youngest-ever and best speakers of the state House of Delegates. In Congress he has forged strategic alliances with key Republicans, thereby breaking from the pack of Democrats who have struggled in an era of GOP dominance to make a mark; he has thus been able to craft important bills to enhance the financial security of retirees and streamline the Internal Revenue Service.
On those measures, his partnership with former representative Rob Portman, an Ohio Republican who is now the White House budget chief, is a textbook lesson in how a minority-party lawmaker can wield influence.
The rap on Mr. Cardin is that he is a legislator's legislator -- a quiet, colorless insider who embodies the system but is ill-equipped to shake it up. In fact, a hallmark of Mr. Cardin's legislative record is tough-minded independence. He was one of a minority of Democrats to vote against the war in Iraq, though once troops were on the ground he acted responsibly by supporting bills to fund and equip them. He broke with many Democrats and labor unions to back the North American Free Trade Agreement. At the same time he has stood against the Bush administration's fiscal recklessness, opposing estate tax cuts for the rich.
Mr. Cardin is a recognized expert on health care, tax and trade policy, and his tough-minded, sensible record has made him one of the House's most respected members on both sides of the aisle.
