The Breakdown: How Can the Democrats Close the Enthusiasm Gap?

Critics ascribed the name "enthusiasm gap" to the tendency incumbent parties have to lose seats during the midterm elections. This article suggest that unlike the 2008 elections, the Democrats (obviously) aren't doing nearly as well as the Republicans in terms of rallying supporters and working to increase voter turnout. In addition, the current state of economy and the nation as a hole isn't working in favor of the Democrats. As a result, Democrats could be likely to lose more seats than we usually observe in midterm elections. Roughly a month before the elections, the democrats' dominant strategy is to contain the "enthusiasm gap" in order maximize their chances of gaining some of the open seats in this elections and decrease the loses they could (will) suffer.
Given the fact that the incumbent parties usually win 90-95% of their seats back, the only efficacious things the democrats can do as this article points out is to minimize the "enthusiasm gap" in the hopes to maximize their chances of winning some open seats.
