Sen. Bill Frist will break with the president, and announce in the morning that he will support stem cell research:

WASHINGTON, July 28 - In a break with President Bush, the Senate Republican leader, Bill Frist, has decided to support a bill to expand federal financing for embryonic stem cell research, a move that could push it closer to passage and force a confrontation with the White House, which is threatening to veto the measure.

Not exactly the way to endear himself to conservative primary voters in 2008. But then, Mr. Frist has not been doing very well in recent polling, anyway.

Update:

Nancy Reagan is with Bill Frist.
