In his second term, President Barack Obama is facing many diverse challenges, as all modern presidents have.
Most recent presidencies have either failed outright in the second term or met such obstacles that the leader’s “legacy” has been greatly affected.
In Obama’s case, it’s a combination of domestic and foreign challenges that, so far at least, is giving the president fits. This is frustrating to his supporters and encouraging to his enemies, who long so much for Obama to fail.
