I've never had any major problems with Justice Anthony Kennedy myself, though it seems that others do. Consequently, Brooks Holland finds it odd that Kennedy didn't make either John McCain or Barack Obama's list of current justices they would not have appointed.
I do not find it that odd, personally (Justice Alito's omission from Obama's list is more glaring). Obama stated his opposition to Roberts, Scalia, and Thomas, while McCain rattled off Stevens, Ginsburg, Breyer, and Souter. In other words (again, with Alito as the exception), the respective right and left flanks of the Supreme Court. Politically, they couldn't go express discontent any further towards the center, because it would make them look radical: "Obama/McCain is so extreme on the judiciary, he wants judges even more liberal/conservative than Tony Kennedy, who actually voted to uphold Roe v. Wade/most abortion restrictions."
The only way either could have put ol' Tony on their list would be by himself, as an example of a judge who is too ad hoc or not principled or predictable enough. That would have been a gutsy move, and I'm not sure how it would have played out, but listing a straight left-to-right or right-to-left line of Justices ending in Kennedy would have been an unmitigated disaster for whoever tried to attempt it.
