Registration changes since the election

2 Comments

I’ve been saving the changes in registration differences in the competitive districts that I track in my regular registration number updates. Here I will show the changes in registration going from the last numbers before the 2008 election to the latest numbers released a few days ago. Here they are in tabulated form. And for the congressional districts, in addition to the 8 Obama-Republican districts, I tossed in CA-04, because the House race there was very close in spite of the considerable Republican advantage in registration and the presidential race, and CA-46, the district of McCain’s closest win of the 11 McCain districts and the only one that he won with less than 50%.

Numbers are over the flip.

  1. Thanks for showing the change from the election.  

    AD-03 looks very interesting.  It shows a dramatic change between 10/08 and 2/09.  Did it really go from R+9.9 to R+4.4 in just 4 months?
