The 7th district can be considered a "safe" GOP seat. Take a look at the primary voter turnout numbers:
7th Congressional District
(2-year term)
(336 of 336 precincts reporting)
29,349 - Joe Schwarz (R-inc.)
33,144 - Tim Walberg (R)
3,004 - Daryl Campbell (D)
2,900 - Chuck Ream (D)
10,366 - Sharon Marie Renier (D)
3,446 - Fred Strack (D)
Even all the Democrat votes combined don't come close to Schwarz's numbers. We had a 19-20% voter turnout.
Thanks, good information.
