Absolutely agree and have been making that argument even before the 2009 Joint Session (see my About page).
There was a substantial failure during the JS of every member of Congress, particularly by our Republicans.
On a quick skim, it appears this court addressed the prior removals by a SoS and nonetheless determined there was no basis for an affirmative ministerial duty by the SoS to investigate a candidate's qualifications. (I do not recall at the moment whether Keyes, et al entered a timely and well supported objection at the primary level.)
Initially thought/hoped Keyes had a shot at the USSC, now not sure.
