The New York Times has an important report in tomorrow's paper about how Miers is being received among GOP Senators:

  The drumbeat of doubt from Republican senators over the Supreme Court nomination of Harriet E. Miers grew louder Tuesday as several lawmakers, including a pivotal conservative on the Judiciary Committee, voiced concerns about her selection.
  Emerging from a weekly luncheon of Republican senators in which they discussed the nomination, several lawmakers suggested that as Ms. Miers continued her visits on Capitol Hill, she was not winning over Republican lawmakers.
 "I am uneasy about where we are," said Senator Jeff Sessions, an Alabama Republican on the Judiciary Committee who had so far expressed only support for the president's choice. "Some conservative people are concerned, that is pretty obvious."

  "I certainly go into this with concerns," Mr. Coleman said.
