Nonpartisanship does not just mean Democrats coaching Little League, lovely as that is, but cooperating with members of the other party in developing compromise solutions to national problems. The Senate has a particularly rich tradition of such bipartisanship, but Mr. Obama appears never to have participated in it. On the contrary: according to Congressional Quarterly, which measures how often each member votes in accordance with or at variance from the majority of his own party, Mr. Obama has compiled one of the most partisan of all voting records.
Throughout his Senate career, according to Americans for Democratic Action, the dean of liberal advocacy groups, ... Mr. Obama voted to ADA's approval more than 98% of the time.
In sum, Mr. Obama comes to us from a background farther to the left than any presidential nominee since George McGovern, or perhaps ever. This makes him an extremely unlikely leader to bridge the divides of party, ideology or, for that matter, race.
