"It is, of course, further indication that a fundamentalist right has really taken over much of the Republican Party, People might cite George Bush as proof that you can be totally impervious to the effects of Harvard and Yale education"

This quote by Barney Frank is referring to the increasing influence of the fundamentalist right within the Republican Party. He is suggesting that although George Bush participated in Harvard and Yale, he is still invulnerable to the effects of the education he received there. This is viewed as more proof of the right's takeover of the Republican Party, as it suggests that even the most elite education is insufficient to counter the impact of the right. Frank's quote is a commentary on the power of the right and how it has had the ability to form the Republican Party in the last few years.
