On the link above you can go back and forth between 2004 and 2008 and see what states changed their political
colors. The following states went from red to blue:
NV, CO, NM,IA, Ind., OH, NC, VA, FL.
There is also a page for an “Intrade forecast” and it mentions states that gained or lost electoral votes since 08.
MA lost one; FL gained two, Ohio lost two etc.
You can thank Section 8 housing used to import Democrat voters.
That is the entire purpose of Section 8.
