Original sentence: However, depending on election timing, it is argued, there may be a significant drop-off in voter turnout in the second round and it is possible that the nominal "majority" winner of the second round may receive fewer votes than the loser received in the first round of voting.In comparison, a two round system (with a majority requirement) will always allow interested voters to participate in the runoff round, and the result satisfies requirements of election by majority.This drop-off did not occur in runoff elections in Cary, NC, where runoffs were held with the general election in November, the primary being held a month before, and this kind of shift of election timing was proposed as an alternative in the debate over Ranked Choice Voting in San Francisco
Edited sentence: In comparison, a two round system (with a majority requirement) requires interested voters to participate again in the runoff round, with the majority threshold ignoring the number of votes cast in the first round.There is almost always a significant drop-off in voter turnout  in either the first or second round in a two-round runoff system, and it is possible that the nominal "majority" winner of the second round may receive fewer votes than the loser received in the first round of voting
