What percentage of the total U.S. homeowner population are democrats,
republicans, and independants? Please cite source.

Hello.

The following data comes from the report, "The Housing Gap: A
Political Analysis of American Voters by Housing Tenure" by Howard
Ernst, University of Virginia, December 15, 1999. The document is
available on the web site goodpolitics.org and consists of three parts
(all are in PDF format and require the Adobe Acrobat reader)

American Voters: Partisan Composition for Each General Housing Type
(Owners & Renters)

Owners
Republicans 38%
Democrats 39%
Independents 23%

Renters
Republicans 23%
Democrats 43%
Independents 34%

(from figure 11.1 on page 17 of Ernst's report).

The report has quite a bit of interesting data on the connection
between housing and political behavior and preferences. For example,
there is a strong relationship between housing status and political
ideology:

Owners:
Liberal 17%
Moderate 41%
Conservative 42%

Renters:
Liberal 36%
Moderate 38%
Conservative 26%

(from figure 15.1 on page 26 of Ernst's report)

search strategy: "republicans own homes"

I hope this helps.
