A Research 2000 Indiana poll was conducted on behalf of the Progressive Change Campaign Committee and Democracy for America from Oct. 24 – Oct. 25, 2009. While there is strong opposition to a public options from those Hoosiers who identify as Republicans, independents and Democrats very much want Sen. Bayh to vote for and not filibuster a public insurance option to compete with private insurers.
Only 33% of independents oppose a government administered health insurance plan. (Along with 10% of Democrats, 75% of Republicans, and 44% of Hoosiers overall.) 59% of Independents, 85% of Democrats, and 20% of Republicans favor such a health insurance plan.
The sample size of the poll was 41% Republican, 36% Democrat and, by extension I suppose, 23% independent.
