Fissures have opened over everything from tax policy and former President Bill Clinton’s off-message comments to recriminations following the party’s fiasco in the Wisconsin recall, which some say should have been avoided.

Democrats disagree over the wisdom of Obama’s attacks on Republican Mitt Romney’s private equity background at Bain Capital and are split over the proposed construction of the Keystone XL pipeline from Canada’s vast oil sands…
