The depth of the 2010 GOP victory in the state legislatures.

It's extreme.

Republicans increased their numbers in 73 state legislative chambers of the 87 up for election. Democrats did get one or two seats in six states: California House (+1), Pennsylvania Senate (+1), Delaware House (+2), Hawaii Senate (+1), Washington State Senate (+1), and West Virginia Senate (+2.)

Compare these tiny gains with the massive Republican gains in many state legislative chambers, like these: Texas House (+24), Pennsylvania House (+14), Ohio House (+14), Ohio Senate (+11), Michigan House (+18) and Michigan Senate (+5), North Carolina House (+15) and North Carolina Senate (+11), Wisconsin House (+26) and Wisconsin Senate (+16), Iowa House (+16) and Iowa Senate (+6), Missouri House (+18), Alabama House (+15) and Alabama Senate (+6), Arkansas House (+12) and Arkansas Senate (+8), Tennessee House (+14), Minnesota House (+26) and Minnesota Senate (+16), New Hampshire House (+117), Maine House (+21) and Maine Senate (6), Connecticut House (+16), Montana House (+18), North Dakota House (+10), and Massachusetts House (+17).

Look at the before and after maps. Click on the individual states to see the particular numbers — for example, in my state, Wisconsin. Look at the swath of states — Iowa, Minnesota, Wisconsin, Michigan, Indiana, Ohio, Pennsylvania — that went from Democrat or divided to Republican. In the south, Alabama and North Carolina went from blue to red. And red begins to creep down from the upper right-hand corner, with Maine and New Hampshire.
