House Democrats have approved the rule for debate on the healthcare bill, moving them one step closer toward a final vote on the legislation.

The rule was passed 224-206, with 28 Democrats voting against the measure. All Republicans cast "no" votes. A procedural vote on the rules passed by a similar count, 228-202.

The tally is a key test vote for Democrats, who hours earlier were able to bring aboard Rep. Bart Stupak's (D-Mich.) anti-abortion rights voting bloc by striking a compromise with the White House.

Under House procedure, lawmakers must approve the rules for debate before taking up actual legislation.

The vote allows formal debate to begin on the healthcare bill. House leaders are eying a vote on final passage later Sunday night.

Here is a list of Democrats who voted "no." 27 of the 28 are listed as "no" votes on The Hill's whip count, with Rep. Harry Mitchell (D-Ariz.) being the only "yes" vote to vote against the rule:

Rep. John Adler (N.J.)
