The Supreme Court opens a potentially epic term Monday that could roil debate in the 2012 presidential election campaign.
The justices have taken a raft of cases that would affect people in their daily lives, including on when police can track their cars with GPS devices and what racy material gets on television when children might be watching.
In coming weeks, the justices will announce whether they will take on two major disputes over federal power, the most closely watched involving the new requirement that most people buy health insurance by 2014. The other concerns Arizona’s law allowing police to check the immigration status of people they have stopped.
