My take on the campain finance opinion and Hamdan? If it takes that many pages to explain, you're probably getting it wrong.
Scalia gets Hamdan in his introductory paragraph. The Court simply did not have jurisdiction to take the case.
Thomas gets it right in his concurrence in Randall.
Sadly, the respondent didn't even challenge Buckley v. Valeo's legitimacy in Randall. (not that he would have succeeded)
