Help the debate moderator summarize the politician's rather contradictory performance by choosing the correct phrase.

The candidate's charisma is undeniable, and he certainly knows how to charm a crowd. _____, his proposed economic policies completely ignore basic mathematical reality.

The correct answer is Be that as it may.

"Be that as it may" is a formal discourse marker used to introduce a contrast or concession. It means "even though that is true, this next part is also true (and usually more important)."

"By the same token" adds a similar point, "Inasmuch as" means "since/because," and "To that end" indicates purpose.
