Rationale

The motives for crossover voting take on many forms. Crossover votes are often strategic, though not necessarily so.^[3] It has been proposed that "mischievous" crossover voting is limited.^[3][4]

Strategic

Insurance

Insurance-purposed crossovers occur when voters see the results of their own party's primary as a foregone conclusion; for example, a candidate belonging to their own party is greatly favored or running unopposed, so their best strategy is to cast a ballot for an opposing party. Two types of insurance-purposed crossover voters exist:

• "Second Best"^[3] voters cross over to vote for an opposing candidate they would prefer over other options in the opposing party, should their own party's candidate lose in the general election. They may be attempting to prevent a candidate they dislike in the opposing party from reaching the general election.
• "Positive Strategic"^[3] voters are unhappy with their own party's leading candidate, and do not see their preferred alternative as viable. Thus, they cross over to vote for a candidate who they think will stand a chance in the general election.

Party raiding

Party raiding is a tactic where members of one party attempt to sabotage another party's primary by voting for an opposing candidate they do not see as standing a chance against their party's candidate,

In some instances, crossover voting may occur when voters feel that the candidate from the opposing party is better. These crossover voters are referred to as "True Supporters",[3] and are not casting their votes for purposes of insurance or sabotage.

In some instances, crossover voting may also occur because no candidate registered with a voter's relevant party filed; therefore if they prefer not to abstain from voting, they must back a candidate from a party other than their own. This form of crossover voting has been referred to as "No Option".^[8]
