It is clear a vigorous debate on the issues could not take place if I remain in the race. What would take place rather is a brutal scorched-earth campaign, the kind of campaign that has turned off so many voters, the kind of politics I refuse to play.Illinois Republican Party leaders were to meet to choose a replacement candidate within a week [to oppose Democrat Barack Obama]. Ryan decided to quit when polls taken after his custody documents were released showed he had a slim chance of winning. The Illinois US congressional delegation unanimously decided Ryan should be replaced. Ryan's fate was sealed after a secret conference call among party leaders. Ryan was accused by his then-wife, television actress Jeri Ryan, of taking her to explicit sex clubs in the 1990s and pressuring her to perform sex acts in public.
