May be a very soft Stupak holdout. This comes from the Houston Chronicle:

WASHINGTON — For Rep. Henry Cuellar, D-Laredo, the turning point may be a letter from Catholic nuns vouching that health care legislation does not promote abortion.
Cuellar is one of a growing number of fence-sitting Democrats who are either declaring support for the $940 billion, 10-year legislation or getting close to doing so. Either way, the momentum Friday definitely favored the Democrats and passage Sunday of a historic measure that promises to make or break their political careers.
“I am almost there,” Cuellar said in an interview, citing “the nuns and other folks” while boasting that he had not even returned a two-day-old phone call from the White House to talk with President Barack Obama.
“I want to make up my own mind,” he said. “At the end of the day, we take a vote.” The president, he said, is “not going to be out there running my election.”
