So, Jude Wanniski is an example of how supply-side economics isn't important in the Republican party because he "was kicked out of the party in disgrace"? So, the fact that he very vocally and very correctly disagreed with the Iraq invasion, and so was shunned by some, means the unrelated ideas he championed, and that are still at least given lip service to, aren't important? Riiiight.
Update: Nice takedown of the piece that Megan is responding to.
