The one-step above toilet paper rags are speculating that the powers-that-be inside the LDP--terrified at the plummeting Abe Cabinet poll numbers--have swallowed their considerable pride and turned to Koizumi to go forth and work some of his electoral magic one more time to save the party in July.
Koizumi is campaigning for Kawaguchi
He owes her big time. Kawaguchi was one his most loyal, self-sacrificing and competent lieutenants. After the chaotic reign of Tanaka Makiko, Kawaguchi pulled the unruly elements of the bureaucracy back into line while maintaining an air of quiet dignity about her. It was Kawaguchi's hard work and dedication that made it possible for Koizumi to play the artless and blithe bon vivant on the foreign stage.
Another reason Koizumi is stumping for her is to fight off questions about her health and vitality. Kawaguchi is trying to recover from Guillain-Barré Syndrome. It is amazing that she is running for a 6-year term. From the statements at the reception, it seems she will likely have to do some of her campaigning from a wheelchair.
Koizumi also knows how to play a good political angle. Kawaguchi, prior to taking over for Tanaka, was briefly Minister of the Environment. Koizumi senses that the environmental story is a winner over the long term--so he is shamelessly plugging Kawaguchi's brief association with it.
Kawaguchi is also one of the Koizumi Kidz, albeit one 66 years old. She won her seat in a 2005 by-election held concurrently with the House of Representatives landslide. Of the top 12 candidates on the LDP party slate for the July elections, she is the only one not the member of any faction.
Finally, love him or loathe him, you have to admit...he knows how to treat a lady who gave of her all for him.
