The quote was from former Federal Judge and informal adviser to Pence, Michael Luttig.
He was discussing the Colorado decision on MSNBC.
He did not seem to predict disqualification saying "if he is to be disqualified".
The words "thinking about it seriously" seem to be key.
' “It is a natural and expected reaction by all Americans,” to think in terms of politics, Luttig said, “But upon thinking about it seriously, I think it’s crystal clear.”
“It will be crystal clear to the American public that it’s the Constitution of the United States that’s disqualifying the former president from higher office, if he is to be disqualified,” he continued. “It’s not President Joe Biden. It’s not the Democrats. It’s not the anti-Trumpers.”
The Colorado Supreme Court determined that Trump was responsible for the Jan. 6 Capitol riots and should be disqualified from the ballot via the 14th Amendment. '
