Fred Barnes’ latest Weekly Standard column explains why presumptive Democratic presidential nominee Barack Obama should think twice about any plans to name rival Hillary Clinton as his running mate:

True, Clinton passes the first test for a vice presidential choice:
she’s a plausible president. But the second test is what one adds to
the ticket. Does she guarantee an Obama victory in a critical state
that he otherwise would lose? The answer is no. But either Governor Ted
Strickland of Ohio or Ed Rendell of Pennsylvania would surely bring
their battleground states if they run with Obama. And Senator Jim Webb
of Virginia would add national security credentials and a populist
economic message to the ticket. Clinton couldn’t match that.
