Did 2001 Gerrymandering Contribute to Congressman Cannon's 2008 loss?

The 2001 redistricting added even more Democrats from the Second Congressional District to the Third Congressional District in an attempt to defeat Congressman Jim Matheson.  Matheson held on, but in the end Cannon did not.  Would Rep Jason Chaffetz have been able to defeat incumbent Chris Cannon in a Republican Primary without the increased number of Salt Lake County voters?

Paul Rolly:  "Weep for the Disenfranchised Voters," focuses on the “shameless gerrymandering” by the Republican majority party in 2001.  Rolly explained that the Democratic voters were combined with conservative voters to take away their Democratic voice and Democratic representation. 

 Utah County’s strong Republican base was gerrymandered into select areas to disenfranchise Democratic voters surrounding Utah County.

Tooele County was chopped up into four different Senate Districts to silence the perceived Democrats living in Tooele County.  You guessed it, part of Tooele County is represented by a Republican senator living in Utah County.

Utah County was also chopped up and has three Senate Districts mixed in with other counties, including Craig Frank’s Senate District, which may have been mixed with Salt Lake County in the original gerrymandering, but was changed by annexing in the Utah County election office
