"“I know – I’m sitting here saying, ‘What are these people smoking?’ You know,
the truth is that Rush Limbaugh has been – he’s ridden the rise of conservatism
for 25 years and I don’t, maybe nobody quite, quite has been following the news,
but that’s coming to an end.”"
I don't think that there is anything that points to this being true. It can be said that people are tired of Bush, and maybe even tired of the Republicans, but many of those people aren't liberals. Many conservatives are tired of Republicans that aren't conservative enough for them.
