Here's a CBS poll from March 23, 2005
http://www.cbsnews.com/stories/2005/03/23/opinion/polls/main682674.shtml (CBS) Americans have strong feelings about the Terri Schiavo case, and a majority says the feeding tube should not now be re-inserted. This view is shared by Americans of all political persuasions. Most think the feeding tube should have been removed, and most also do not think the U.S. Supreme Court should hear the case.
An overwhelming 82 percent of the public believes the Congress and President should stay out of the matter. There is widespread cynicism about Congress' motives for getting involved: 74 percent say Congress intervened to advance a political agenda, not because they cared what happened to Terri Schiavo. Public approval of Congress has suffered as a result; at 34 percent, it is the lowest it has been since 1997, dropping from 41 percent last month. Now at 43 percent, President Bush’s approval rating is also lower than it was a month ago.
Here's an April 11, 2005 USA Today article titled "GOP's Moral Agenda Doubted"
http://www.usatoday.com/news/washington/2005-04-05-gop-poll_x.htm WASHINGTON — The controversy over Terri Schiavo has raised concerns among many Americans about the moral agenda of the Republican Party and the political power of conservative Christians, a USA TODAY/CNN/Gallup Poll finds. (Related: Poll results) In the survey, most Americans disapprove of the efforts by President Bush and Congress to draw federal courts into the dispute over treatment of the brain-damaged Florida woman. She died last week.

By more than 2-to-1, 39%-18%, Americans say the "religious right" has too much influence in the Bush administration. That's a change from when the question was asked in CBS News/New York Times polls taken from 2001 to 2003. Then, approximately equal numbers said conservative Christians had too much and too little influence.
The National Journal "Public to Politicians: 'Keep Out'" (April 5, 2005)
http://www.theatlantic.com/doc/prem/200504u/nj_schneider_2005-04-05There is evidence of a backlash. A Gallup Poll taken just before Bush and Congress acted in the Schiavo case showed the president with a 52 percent approval rating. But in the Gallup Poll taken just after he signed the bill giving federal courts jurisdiction over the case, his rating fell to 45 percent. CBS News polls show a similar decline in Bush's ratings, from 49 percent in February to 43 percent after he signed the Schiavo bill.
Now granted, I don't think the Schiavo incident is the only or even a primary reason the GOP got hammered last fall, but it was one ingredient in some mighty tasty stew. I think mainstream America is genuinely repulsed when they see how little respect for individual privacy or autonomy the RW Culture Warriors actually have and that it would be foolish to emulate them.
