Senate Democrats on Wednesday proposed allowing the federal government to borrow an additional $1.9 trillion to pay its bills, a record increase that would permit the national debt to reach $14.3 trillion.

The unpopular legislation is needed to allow the federal government to issue bonds to fund programs and prevent a first-time default on obligations. It promises to be a challenging debate for Democrats, who, as the party in power, hold the responsibility for passing the legislation.

It's hardly the debate Democrats want or need in the wake of Sen.-elect Scott Brown's victory in Massachusetts. Arguing over the debt limit provides a forum for Republicans to blame Democrats for rising deficits and spiraling debt, even though responsibility for the government's financial straits can be shared by both political parties.
