It already HAS been the (D) goal, for 6 years, ever since they gerrymandered the district specifically to get him out.  But he just keeps winning anyway, wasting those limited (D) voters they shifted into his district trying to oust him.  

Pretty amazing that he's foiled their plan for 3 of the 5 terms already.  They might finally defeat him for the final 2 terms of the decade, but overall Coffman has won the decade and defeated the gerrymander.

It all starts over in 4 years, where there will be an entirely reshuffled map as we expand to 8 districts.
