WASHINGTON — It has been a mixed week for Sen. Barack H. Obama, the presumptive Democratic presidential candidate. On the one hand, a Reuters/Zogby poll announced that the junior senator from Illinois' 7-point lead over Sen. John McCain, the presumptive Republican presidential candidate, has dissolved into a 5-point deficit. McCain now leads him 46 to 41 percent. On the other hand, the media have discovered Sen. Obama's long-lost half brother George Hussein Onyango (also spelled Owango) Obama living quietly in Kenya. Among the rustics who constitute the Democratic base, this discovery can only help Sen. Obama.

According to the Reuters/Zogby poll, the Democratic front-runner has slipped with almost every category of Democratic voter: Catholics, evangelicals, vegetarians, nudists, flagpole sitters — you name it. Yet the slippage has been greatest among the senator's core supporters, the liberals. Among them he has dropped 12 percent. Part of the reason for this drop, Zogby speculates, is owing to the candidate's efforts to sidle toward the political mainstream. Zogby mentions Sen. Obama's switch from opposing all offshore oil drilling to accepting limited drilling.

Brother George will assuage the concerns of many of these liberals. According to the Italian edition of Vanity Fair, George lives in a hut in bucolic Huruma, Kenya, a few miles outside Nairobi. His residence is the epitome of "green," using no electricity, cooled solely by gentle breezes, and with no plumbing to pollute nearby waters, if there are nearby waters. George leaves almost no carbon footprint. He does not drive an automobile. In fact, he lives a very Spartan existence, spending only "a dollar a month," as he apprised VF in an exclusive interview; though other sources report an expenditure of a dollar a day. At any rate, his consumption of the world's resources is minimal.

Actually, it is not completely accurate to say George is Sen. Obama's "long-lost" sibling, for Barack met his brother when George was 5 years old, two decades ago. In "Dreams from My Father," Sen. Obama's autobiography, he recalls George as a "beautiful boy with a rounded head." As a writer, the senator has an eye for detail. George tells VF that the two met again in 2006, when Sen. Obama was touring East Africa and visited Nairobi. Apparently, the meeting did not go well. As George recalls it: "We spoke for just a few minutes. It was like meeting a complete stranger." George is only 26, which could help his brother shore up the youth vote back in the United States, a vote that is often unreliable.

Frankly, I find it curious that Sen. Obama has not brought George onto the campaign trail with him. Perhaps he has been saving George for the Democratic National Convention. The convention will abound with so many of the enthusiasts who, in the recent primary season, plucked Illinois' junior senator from relative obscurity and elevated him above the likes of Sen. Hillary Clinton and the widely admired former Sen. John Edwards in the presidential sweepstakes. I have in mind the environmentalists, the enemies of the giant corporations, the Angry Left, the Even Angrier Left — most of whom never have dirtied their hands in politics or, for that matter, any civic involvement whatsoever.

In his VF interview, it is apparent that George is well-spoken and has experienced the ups and downs of life that are so enrapturing to Democratic convention goers — particularly the downs. Moreover, it would be prudent to get George out of Kenya, where his presence could be a Secret Service nightmare. For that matter, Sen. Obama has seven other half brothers living in far-flung habitats. The Secret Service will have its hands full keeping an eye on them.

If brother George does make an appearance at the Democratic National Convention, he surely will outshine Sen. Hillary Rodham Clinton's brothers, who were so deeply implicated in the brokering of President Bill Clinton's last-minute pardons and in other questionable financial deals in the 1990s. Sen. Obama's boast of being aloof from the "same old Washington politics" can be reinforced only by his brother's presence at the convention. George Hussein Onyango (also spelled Owango) Obama is the farthest thing from being one of those "Washington insiders" his brother inveighs against. Finally, given our country's low estate within the world community, who would make a more agreeable United States ambassador to the United Nations than this exemplary Citizen of the World, George H.O. Obama?

Sen. Obama's decline in the polls may be over.
