FiveThirtyEight: Senate Forecast, 7/18: Republican Outlook Improves with Focus on Likely Voter Polls
Our latest Senate simulation has the chamber convening in 2011 with an average of 53.4 Democrats (counting Joe Lieberman and Bernie Sanders), 46.1 Republicans, and 0.5 Charlie Crists. This is an improvement for Republicans from our last forecast three weeks ago, which had 55.2 Democrats, 44.2 Republicans, and 0.6 Crists. The changes, however, predominantly reflect several methodological improvements we have made rather than any particular national momentum, although the dynamics of some individual contests are certainly evolving.
