It’s a virtual article of faith among election analysts that Republicans will gain Senate seats in the 2014 midterms. I tend to agree with that assessment, and strongly so. In fact, like other forecasters such as Alan Abramowitz and Nate Silver, I think Republicans have the edge in the battle to take control of the upper chamber this November.
But there is one place where I part company with most forecasters. I’m not 100 percent confident that Republicans will gain seats. In fact, when I analyzed the Senate races in February, my simulation created a few scenarios where Republicans did, in fact, lose seats. (It’s also worth remembering that while a seven-to-nine seat Republican gain was the most likely scenario, in about 60 percent of the scenarios, Republicans gained some number other than seven, eight, or nine.)
The first thing that would have to happen is that the playing field would have to improve for Democrats. Of the 11 Democratic seats that RCP currently rates as leans Democratic or worse, Democrats are probably at least slightly favored in Michigan, Iowa, New Hampshire, and perhaps Colorado. If the political dynamic were to shift toward the party, these seats would probably be out of the GOP’s reach on Election Day.
