"If Rush Limbaugh wants President Obama to fail, he wants America to fail. Is that what you all want too??? "

No!! That's NOT what Rush said. You obviously disagreed with all or most of Bush's policies and obviously wanted him to fail in enacting those policies because you thought that that was bad for the country. Yet, I presume (hope) that you were not hoping that America would fail as well. So, yes, it is very easy to hope that Obama fails (to enact his policies) because you WANT America to succeed.
