The bipartisan spirit of McCain's long collaboration with Edward Kennedy and other Democratic senators is no surprise. McCain calls Kennedy "the lion of the Senate," as indeed Teddy is - perhaps our finest senator ever. Jack Kennedy, too, was bipartisan, appointing two Republicans to his cabinet. McCain, one of the two or three most bipartisan national figures of our day, has worked with Democrats on the environment, court appointments, campaign finance, immigration and more. Obama has the most extreme partisan voting record of any senator. Now, gambling his candidacy on a dynamic young Alaska governor, McCain has confirmed his independence as a leader not bound by the insider politics of Washington.
