Finding The Split In The Republican Party

In 1861, the Confederate States of America seceded from the United States of America. The map below shows the Confederacy in green (with light green showing territory claimed by the Confederacy without formal secession).

Today, the same geographical split exists. But it exists inside the Republican Party.

Last week, the House of Representatives passed the American Taxpayer Relief Act -- a tax cut of more than $3 trillion over the next 10 years. The bill passed by a vote of 257-167.
In order to prevent the "fiscal cliff", this bill required some degree of bipartisan support. And John Boehner (R-OH) managed to convince 36% of his caucus to vote for the bill.

However, the vote breakdown shows a huge geographical split inside the Republican Party:

	For	Against	Support
Original Slave States (1776)	1	29	3.3%
The South	18	84	17.6%
The Northeast	25	2	92.6%
TOTAL	85	151	36.0%

Here is a map showing the breakdown by state. Orange shows where a majority of the Republican Representatives voted for the bill. Red shows where they opposed the bill decisively (by 3 or more votes).

This shows a split in the House that isn't between Republicans and Democrats. It's between Northern Republicans and Southern Republicans.
