Hold On To Your Hats

It should be noted . . . that this year's 15-point gap in favor of the Republican candidates among likely voters is unprecedented in Gallup polling and could result in the largest Republican margin in House voting in several generations. This means that seat projections have moved into uncharted territory, in which past relationships between the national two-party vote and the number of seats won may not be maintained.

From Gallup's lips to God's ear.  Note, however, that the results require a strong Republican turnout!
