I don't agree at all that she is a big risk.
Obama is a calm, self-confident person, one moreover who already has gone toe-to-toe with Clinton during the primaries.
He won those confrontations. Hillary was the one off brooding in a corner.
Her sleazy husband was ferociously angry by all reports and kept telling his friends that Obama could never win.
Guess who won and won big?
The immense concessions the Clintons have made - approval of sleazy Bill's speaking engagements and a full vetting of his contributors - really show a complete humbling of their pride.
And Obama has her inside the tent peeing out rather than outside peeing in.
