I said earlier that we would probably have to wait until after 2008 to see if the Democratic majority sticks and officially puts an end to the 26 year-old conservative era. I mean that more than just if a Democrat gets elected President in 2008, but the entire election in general.
First, it's important to realize the Republicans have the upper hand in 2007 elections. Three gubernatorial races are to be held, all in red states. Only Kentucky looks to be really competitive. Republicans have a huge chance for a pickup in Louisiana and look safe to reelect Haley Barbour in Mississippi. Kentucky really depends on the GOP primary, and even then, it appears to be a tossup.
In 2008, however, everything is up for grabs, the entire House, many of the most competitive Senate races, a slew of competitive gubernatorial races, and of course the crème de la crème, the White House.
Democrats, barring any major mishap, will probably keep their House majority. They will likely lose a few seats and gain a few they didn't gain in 2006. The important thing about the 2008 House Races is what will happen to the Democrats elected in Republican-leaning districts. Many of these Democrats are rather moderate to conservative and play well to Republicans in their district, but 2006 ushered in a whole gang of progressive, liberal Democrats in districts Bush won. Democratic freshmen, like Carol Shea-Porter of New Hampshire, John Hall of New York, Zack Space of Ohio, Steve Kagen of Wisconsin, Ciro Rodriguez of Texas, Nancy Boyda of Kansas, Harry Mitchell of Arizona and Jerry McNerney of California all have voting records in their first months much farther to the left of their predecessors and sit in districts that have leaned Republican in the past. Their survival, coupled with how the Democratic nominee for President plays in their districts, may help judge the future of the Democratic majority and may confirm if there is in fact a New Democratic Era. Also in question is the survival of GOP House members who barely made it through last November. Republicans like Jim Gerlach of Pennsylvania, Christopher Shays of Connecticut, Jim Walsh, Peter King, and Randy Kuhl of New York, Mike Ferguson, Jim Saxton, and Frank LoBiondo of New Jersey, Mike Castle of Delaware, Deborah Pryce and Jean Schmidt of Ohio, Robin Hayes of North Carolina, Vern Buchanan of Florida, Heather Wilson of New Mexico, Peter Roskam of Illinois, Barbara Cubin of Wyoming, and Dave Reichert of Washington all sit in seats that either lean Democratic and/or were nearly taken by the Democrats in 2006. These incumbents are going to be the Democrats' biggest targets in 2006 and many are facing the same competitive Democrats they barely defeated this past year. Some of these Republicans may retire, but if many of the aforementioned Republicans do not survive reelection campaigns in 2008, it could be a bright neon sign that the Republicans are looking at a long minority presence.
The Presidential race steers all else. A strong Democratic candidate may very well pull off a Democratic version of 1980, pulling many of the mentioned GOP House seats, competitive Senate races, such as the ones in Maine, New Hampshire, Minnesota, Colorado, New Mexico, Oregon, Virginia and possibly North Carolina, Texas and Oklahoma, while defending their potentially competitive seats in Louisiana, Arkansas, Montana, and South Dakota . Democrats can also use the nominee's coattails to defeat Republican governors in Missouri, Indiana and Vermont who may face close races, and protect their incumbent Governors (or open seats,) in Washington State, Delaware, North Carolina and West Virginia.
Rahm Emanuel was right when he said it is important the Democrats do not blow it in 2008. Their majority is still fragile and young and has the potential to reformat itself into a generation-long majority if they choose the right people with the right ideas that appeal to the population as a whole, (think Ronald Reagan here.)
If not, their majority might be no more than a short-lived Indian summer, but right now, the wind is with the Democrats, they just need to raise the sail right.
