NYT:
Republicans, who are modest favorites to take over the House from Democrats, still have a chance to do the same in the United States Senate. But their odds have dropped significantly: from a 26 percent chance last week to 15 percent today, according to the FiveThirtyEight forecasting model.
The main reason for the decline is the outcome of Tuesday’s Republican primary in Delaware, in which the insurgent candidate, Christine O’Donnell, defeated Michael N. Castle. Two recent polls, including one completed after the primary, show her trailing her Democratic opponent, Chris Coons, by margins of 11 percent and 16 percent.
