For inveterate political junkies watching tonight’s all-Republican runoff in Louisiana’s 3rd District, the last member-member race of the year, I’ve prepared this quick map showing the old CD03 (Rep. Jeff Landry) and CD07 (Rep. Charles Boustany) laid over new CD03 results from November. As you can see, the largest parishes of the new district are in Boustany’s old district (Lafayette and Calcasieu Parishes), and that every county voted for their incumbent. Similarly strong geographic splits were mapped in Pennsylvania’s member-member races earlier this year.
P.S. – I take custom commissions for county & precinct election maps. Want one hanging on your wall? Click here.
