Now that Hillary Rodham Clinton is running for President it is easy to forget that she has already demonstrated her commitment not only to the citizens of this country but to her fellow Democrats. Starting from her first days in the Senate, Senator Clinton made it clear she was there to work with her fellow Senators, not ride roughshod over them. She worked hard for John Kerry and for Al Gore. When Joe Lieberman left the Party, Senator Clinton made clear her commitment to the Democratic Party again: she would, and did, support the Democratic nominee for the Senate seat in Connecticut. These measures - and they are just the tip of the iceberg - reveal that Senator Clinton genuinely appreciates that the Democratic Party is not about one politician: it is an institution that aspires to help all Americans. Being loyal to the D.N.C. and to her colleagues is not a matter of "old politics". It is a sign of political wisdom.
