SurveyUSA interviewed 630 registered voters in the state of Missouri and asked about a number of different ways in which the Super Committee of the U.S. Congress might reduce the national debt.

* 63% of voters say that if U.S. Senator Claire McCaskill (D-MO) backs a plan to cut Social Security benefits, they would be more likely to vote against her.
* 53% of voters say that if McCaskill backs a plan to cut Medicare benefits, they would be more likely to vote against her.
* 49% say that if McCaskill backs a plan to extend permanently the Bush tax cuts, they would be more likely to vote against her.
* 49% say that if McCaskill backs a plan to raise from 65 to 67 the age at which Americans become eligible for Medicare, they would be more likely to vote against her.

By contrast:
* 60% of voters say they would be more likely to vote to re-elect McCaskill if she backs a plan to raise taxes on those making $1 million a year.
* 54% of voters say they would be more likely to vote to re-elect McCaskill if she backs a plan to raise taxes on those making $250,000 or more a year.

Cell-phone respondents and home-phone respondents included in this research. SurveyUSA interviewed 700 state of Missouri adults on 11/17/11. Of them, 630 were registered to vote and were asked the substantive questions. This research was conducted multi-mode. Respondents who use a home telephone (78% of registered voters) were interviewed on a home telephone in the recorded voice of a professional announcer. Respondents who do not use a home telephone (22% of registered voters) were shown a questionnaire on their smartphone, laptop, tablet, or other electronic device.
