With a House vote expected later this week, Connecticut voters disapprove of health reforms, 48 percent to 40 percent, according to a Quinnipiac University poll released today.

But the poll found 70 percent believe that Congress should keep trying to pass a health reform bill, with the heaviest support coming from Democrats (88 percent) and independents (70 percent).

There are deep differences among Democrats and Republicans, with Democrats saying they "mostly approve" the pending health care changes, 68 percent to 22 percent.

Republicans disapprove, 87 percent to 7 percent. Independents disapprove, 50 percent to 34 percent.

Fifty-two percent said the changes would be too expensive and 35 percent said costs would be "about right."

Again, 57 percent of Democrats expected the cost to be about right, 82 percent of Republicans and 55 percent of independents said it would be too expensive.

When asked if government should require all Americans to have health insurance, with tax credits or other aid to help low-income people pay for it, 60 percent said it should be required.

Eight-two percent of Democrats and 58 percent of independents favored mandatory coverage, while only 29 percent of Republicans were in support.

All groups strongly favored requiring insurance companies to sell coverage regardless of pre-existing conditions.

Excluding pre-existing conditions was favored by 83 percent of all respondents, 72 percent of Republicans, 91 percent of Democrats and 84 percent of independents.

The poll is based on a telephone survey of 1,451 registered voters from March 9 to 15. It has a margin of error of plus or minus 2.6 percentage points.
