◼ A definitive guide to the 2014 elections - Politico
Ultimately, the 2014 battle for the Senate, which Democrats now hold 55-45, is close. It will be an enormous shock if Republicans do not gain seats and at least reduce the margin of Democratic control. If the GOP can restrain its cannibalistic instincts and tendency to nominate flawed candidates, then to retake the Senate it need only match the post-World War II average gain of six seats for the party out of power in the White House in the sixth year of two-term administrations. At this point, I’d set the over/under on Republican gains in the Senate at 3.5, and I’d take the over—meaning a net gain of four or more Senate seats for the GOP. If Republicans end up dipping under, they will have had their third consecutive underperformance in Senate contests. On the contrary, if even a modest-sized wave develops for Republicans next fall, the third time could be the charm for the GOP’s goal of a Senate takeover.
The ebb and flow of politics is one of the few constants throughout American history, and 2014 will be no exception. The GOP fared well in 2002 and 2004, then it was the Democrats’ turn in 2006 and 2008. Since then, the back-and-forth cycle has speeded up, with Republicans winning handsomely in 2010 and Democrats in 2012. In the quick “surge and decline” politics of our highly polarized era, the early bet has to be on Republicans to do well in 2014—despite themselves.
