Unlike their first debate, a typical TV face-off, the two candidates weren't even in the same room.  Fiorina was at the studios of public radio station KPCC in Pasadena, which hosted the hour-long program.  Boxer joined in from NPR in Washington.  But just like their first debate, the candidates made their political differences clear.  Boxer criticized Fiorina for supporting drilling for oil off the California coast … and the suspension of the state's landmark global warming law.

Boxer: "So she stands with Big Oil.  She doesn't stand with the people of California.  They revere their environment.  It is a God-given gift and it also is an economic asset."

But Fiorina called Boxer's leadership atop the Senate's Environment and Public Works committee a failure, saying Boxer is too polarizing and supports extreme environmental causes.

Fiorina: "I oppose Barbara Boxer's cap-and-trade bill.  It has been called the most expensive piece of legislation in U.S. history.  Economists agree it would cost this nation millions of jobs."

The two also clashed on the economy, immigration and abortion.  No other debates are scheduled between now and Election Day.
