If conservatives know that Obama's plans arn't going to work then how come they've been wrong everything?

tax cuts for the rich didn't help, no connection between alqaida and saddam,no weapons of m destruction, no new good jobs anywhere other then walmart fall apart, 4000+ waisted lives on sand and explosives in iraq. nation building when bush clearly states on youtube video debates that he wouldn't nation build? he did get us attact he was on vacation for nine months that might be part of his problem you think?
