A Danish Party Cohesion Cycle

The aim is to analyze short-term fluctuations in Danish parliamentary party cohesion on the backdrop of an American electoral pattern in party cohesion. A Danish cycle is documented: party cohesion in relation to voting behavior is especially high just after an election, then it drops to rise again as election time approaches. A rational choice re-election model predicts the rise in party cohesion, but an obligation actualization model predicts the full cycle. Elections actualize Danish MPs' moral obligation to their party. Where American party cohesion drops in an election year, Danish party cohesion rises when an election approaches. This may be explained by different preferences in the American and Danish electorates: Danish voters value party cohesion per se , American voters do not.
