Peter Foster: US Presidential debate - Can Joe Biden clean up the mess Obama made?
OFTEN in US election cycles, the vice-presidential debate is considered an entertaining but largely inconsequential diversion: politicos might be curious to see how the understudies perform, but the voting public really has eyes only for the two principals.
Not this time. After Barack Obama slept-walked through the first presidential debate in Denver, precipitating a revival for Mitt Romney in the polls, the heat is now on Joe Biden to help put a stop to the Romney roll.
It is an unaccustomed role for Mr Biden, a loquacious but notoriously unreliable politician who over the last four years has played fool to Obama's Lear, speaking truth unto power, keeping the Obama White House 'intellectually honest', as one staffer recently portrayed it.
