The primaries—added with Democrat retirements and scandals—have made it more like Republicans will win the U.S. Senate in November. The Washington Post,
“These past seven days typified the fates of the two parties this election cycle. Democrats have been hit by retirements in tough states — Montana, West Virginia, South Dakota and, to a lesser extent, Iowa — and Republicans haven’t nominated the sort of extreme candidates who lack broader appeal in a general election.
“Those realities — along with a national playing field in which a handful of incumbent Democrats are defending Republican-leaning seats in places where President Obama is deeply unpopular — have made a GOP takeover a better-than-50/50 proposition.”
