Despite the stereotype, typically the economy sucks under republicans and is repaired by democrat (Eisenhower is an exception, and Roosevelt took a while to figure out what to do, but I did say "generally"). Remember the concern under Clinton that the national debt might be retired and what a disaster that would be?

Since I'm in the realm of gross generalizations it's often under Democrats that wars have ramped up: well, Roosevelt again, Kennedy and Johnson Vietnam, and, yes, Obama on the secret side) while republicans can close them off: Nixon (Viet nam & the cold war with China, Reagan/Bush sr Cold War with Russia. But this link is even more tenuous.
