TOKYO (Reuters) - Tokyo Governor Yuriko Koike, whose new party is challenging Japanese Prime Minister Shinzo Abe s ruling bloc in the Oct. 22 national election, said she would  100 percent  not run in the poll, the latest twist in a drama giving voters whiplash. Speculation has persisted that Koike, a former LDP member and defense minister, would resign to run for a seat in parliament needed to make a bid for the premiership.  I have been saying I will not run for the election from the beginning,  Koike said in an interview with the Yomiuri newspaper reported on Tuesday.  I m 100 percent not running for the election.  She later repeated the comment to reporters.  If Koike does not personally contest this election, then analysts believe she would hope her party positions itself to win the next national poll, and that she gains a voter boost from the 2020 Tokyo Olympics.  Abe announced the snap election last week in hopes his Liberal Democratic Party-led coalition would keep its majority in parliament s lower house, where it held a two-thirds  super majority  before the chamber was dissolved. But Koike s new Party of Hope - launched just last week as a  reformist, conservative  alternative to Abe s equally conservative LDP - has clouded the outlook amid signs voters are disillusioned with Abe after nearly five years in power. Koike s dilemma was whether to run for a seat now and face a backlash from voters for quitting as governor little more than a year since she defied the LDP to run successfully for the post, or risk letting a shot at the top job slip through her fingers. Some analysts saw her decision not to seek a seat now as a sign Koike thinks her party s momentum is fading.  She must have thought it would not be worthwhile abandoning the post of Tokyo governor to become a head of an opposition,   said Tetsuro Kato, a professor emeritus at Hitotsubashi University. Koike has been getting negative media coverage for saying she would  exclude  candidates who do not agree with her party s policies - a stance seen as barring liberal members of the failed main opposition Democratic Party from joining. Leaders of the Democratic Party - a fractious mix of conservatives and liberals - decided last week it would not run candidates of its own but let members run from Koike s party. Koike s comment was applauded by some as an effort to ensure policy consistency but by others as a dictatorial maneuver.  She s branding a very new party and has to make clear what it stands for, but the danger is that while Abe owned the  arrogance of power  space, she is now vying for some of that,  said Jeffrey Kingston, director of Asian studies at Temple University Japan.  Abe s support rates fell earlier this year due to suspected cronyism scandals and many voters  perception that he had grown complacent and arrogant after nearly five years in office.  His rating later rebounded but dropped again to 37 percent in the latest poll by public broadcaster NHK. Koike s party is insisting those who want to run on its ticket sign a policy pledge, including revising the pacifist constitution and exercising the right of collective self-defense, or militarily aiding allies under attack-defense, a document seen by Reuters showed.  Many liberals balk at those policies. Koike s party on Tuesday unveiled a list of 192 candidates for the lower house election. That compares with 233 seats needed for a simple majority.  The party plans to announce more candidates in the coming days, but a senior party member conceded that it will be a tall order to win a majority.   Although (fielding) 233 candidates is a very high mountain, we would like to finish climbing it. On the other hand, in actuality, it would be considerably difficult for us alone to gain a majority even if we fielded 233,  said Goshi Hosono, a founding member of the party and former environment minister.   Further complicating the outlook, liberals from the Democratic Party launched a Constitutional Democratic Party of Japan. The CSDP could split the opposition vote and help Abe s bloc keep its majority, but by how much is tough to predict.  Koike is tough, she s resilient and she can tap into the fact that Abe s negative ratings are pretty high and a lot of people out there are unhappy with him,  Kingston said.
