Before we crunch the numbers, we should note that the patterns below can't be linked exclusively to Dean's 50-state project. After all, the Democrats experienced two of their strongest election cycles during that time. They benefited from a strong congressional tailwind in 2006 and a winning presidential candidacy in 2008. Meanwhile, the numbers began to turn negative during the midterm election of 2010, a Republican rout.
That said, the patterns are suggestive. In the 20 states we looked at -- those that have voted solidly Republican in recent presidential races -- Democratic candidates chalked up modest successes, despite the difficult political terrain. Then, after the project stopped, Democratic success rates cratered.
The 20 states we looked at are Alabama, Alaska, Arkansas, Georgia, Idaho, Kansas, Kentucky, Louisiana, Mississippi, Montana, Nebraska, North Dakota, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia and Wyoming. We excluded any state that has voted Democratic in recent presidential contests or was considered potentially competitive for the Democrats, even if the state ultimately sided with the GOP (such as Arizona and Missouri).
Here's how the Democrats fared in the reddest of red states between January 2005 and January 2009, the period when the 50-state project was in operation:
State House seats: Net gain of 39 seats, a 2 percent increase of all seats in the states analyzed
State Senate seats: Net loss of two seats
Governorships: Net loss of one
Attorney generalships: Net gain of one (elected seats only)
U.S. House seats: Net gain of three seats
U.S. Senate seats: Net gain of one seat
Presidential performance: In 15 of the 20 states, the Democratic nominee saw an increase in vote share between 2004 and 2008. In three other states, the vote share remained constant. It dropped in only two states.
"Where we really made a big difference was in states like Nebraska, where Obama won an electoral vote in 2008," Dean said. "He had a real party to work with."
Overall, Democrats either improved their results in the reddest states between 2005 and 2009 or, at worst, suffered only minor setbacks, which, given the obstacles the party faced in these solidly Republican states, was almost a victory in its own right.
Now let's compare this record to the one between January 2009 and January 2013.
State House seats: Net loss of 249 seats, a decrease of 13 percent of the existing seats in those states
State Senate seats: Net loss of 84 seats, a decrease of 12 percent
Governorships: A decrease by half, from eight governors to four
Attorney generalships: A drop by two-thirds in elected AGs, from nine to three
U.S. House seats: A 40 percent drop, from 44 seats to 26
U.S. Senate seats: A drop from 11 seats to 8. (It could drop further by 2014: Of those eight remaining seats, three senators are retiring and another three face tough reelection contests.)
Presidential performance: Only two of the 20 states (Alaska and Mississippi) saw higher support for Obama in 2012 than in 2008. In most of the 20 solidly red states, Obama's 2012 vote fell back roughly to John Kerry's level from 2004.
Altogether, these post-2009 declines are, to put it bluntly, pretty catastrophic. In these 20 solidly red states, the Democrats controlled 13 legislative chambers in 2005, a number that fell to just three in 2013. Of the 40 chambers in these states, only two experienced a net gain of Democratic seats between 2005 and 2013; in the other 38, the Democrats lost ground.
And because state legislative seats and lower statewide offices provide the "bench" for future runs for governor and Congress, these developments could prompt a self-perpetuating death spiral for the party in these states.
