Rigging elections. The Census is now complete, which means that the gerrymandering drawing of districts can now commence. The Democrats are angry because they don’t rule Florida’s electoral process. The areas of Florida that have historically voted Democrat are the southeast coast near Miami, and the area around Jacksonville. (The 2008 election saw other areas in blue, but in my opinion that was more a result of the Democrats all running against former President Bush than a true shift in political power.)
To counter this, the Democrats want to redraw districts to create an advantage for themselves. It won’t work. You cannot thwart corruption in politics.
