DKE has a nice breakdown of the new districts (they also did one for California):

I don't understand why Mica is running in FL-07, when FL-06 is mostly from his old district and it's more Republican.
Also, Crist won three of the districts in 2010, FL-13 (Bill Young), FL-21 (Ted Deutch), and FL-23 (Debbie Wasserman Schultz). Edit: four, actually, he won FL-14 (Kathy Castor) by a hair.
Comparing Obama/McCain results for the old and new districts:
Old: 10 Obama - 15 McCain
New: 10 Obama - 17 McCain
All six Dem-held CDs (Brown, Castor, Wilson, Deutch, DWS, Hastings) all heavily Obama before and after.
Bill Young's CD stays at 51-47 Obama.
Ileana Ros-Lehtinen's CD goes from 51-49 Obama to 51-49 McCain.
Daniel Webster's CD (Alan Grayson's old CD) is currently 53-47 Obama, and will be split into a (likely) Grayson CD at 60-39 Obama and a Webster CD at 52-47 McCain.
Allen West's old CD is 52-48 Obama and Tom Rooney's is 52-47 McCain. West will be running in Rooney's old CD at 51-48 Obama. The successor to Allen West's old CD is 57-43 Obama.
BTW, can someone explain the headings in the Fla. (and Calif.) expanded spreadsheet?
