House Democrats today plan to offer an alternative to a Republican health care "fix" for Obamacare that is similar to a bill authored by Sen. Mary Landrieu, D-La.

A top Democratic House aide said Friday that the measure, like Landrieu's plan, would allow people to keep individual health insurance policies that were cancelled because they do not meet the benefit requirements under Obamacare.

The House Democratic measure would limit the extension of old policies through 2014, and insurers would not be able to sell the policies to new customers, which is allowed in a GOP proposal already set for an early afternoon vote.

The Democratic proposal would also grant the Department of Health and Human Services and state insurance commissioners the power to "go after bad-actor insurance companies and take corrective measures against excessive, unjustified, unfair and discriminatory rates," the aide said.

The House early Friday was already debating the GOP bill, authored by House Energy and Commerce Committee Chairman Fred Upton, R-Mich.

Republicans are calling their proposal a "lifeboat" for those who have suddenly learned their health care policies have been canceled. Democrats say the GOP measure is a political stunt that will undermine Obamacare by destroying the health care exchanges needed to make Obamacare financially viable.
