Invoking the Cloture Rule. Page 344 in Magruder's AM book.
No, the vice president cannot break a tie for cloture in the Senate. Cloture requires a three-fifths majority (currently 60 votes) to end a filibuster and bring a bill to a vote. The vice president's role is primarily to cast tie-breaking votes in the Senate, but cloture votes specifically require a majority of those present and voting. Thus, if the vote on cloture is tied, it fails.
