Are the elections being held under the 2010 lines (which these two Senators were last elected from) or the new lines (which Senators will be elected from in 2014 and which I assume half of the members of the Colorado Senate were elected from in 2012)? I'm not sure how much the lines are different.
I answered my own question with like 95% certainty. I'm pretty sure the new lines will be used, which I'd say makes sense since already about half the Senators represent the new districts. See
http://www.krdo.com/news/frequently-asked-questions-morse-giron-recall-elections/-/417220/21805222/-/s15jrs/-/index.html and then click on the "Senate District 11" link (the resulting PDF has a caption that reads "Prepared by the Reapportionment Commission Staff [new line] December 2011"). I would assume the same vintage lines would be used in Senate District 3. The pro-recall of John Morse site
gotremorse.com (cute) also states, "Due to recent gerrymandering changes to the Senate districts, some people are no longer certain what district they may currently reside in." There's no specific mention of the lines being different from either the last State Senate election in that district or the next one, but the implication is that the lines used in the recall will be different from those used in 2010 (so likely the same as those used in 2014).
