The Democratic establishment, led by President Obama, came out on top Tuesday, delivering a string of blows to progressive challengers who party leaders decided were not their best candidates to help claim the Senate this fall.
The fallout from these victories remains to be seen. The sheer amount of money poured into Senate primaries in Pennsylvania and Maryland -- close to $30 million in Democrat-on-Democrat spending -- along with the vitriol of the intraparty attacks begs the question about how unified Democrats will be in November.
"I think people will come back on board, but it's going to take some work," Sen. Jon Tester (Montana), chairman of the Democratic Senatorial Campaign Committee, said in an interview Tuesday afternoon.
The establishment triumph demonstrates that Democrats have not drifted anywhere close to the upside-down world of Republican primaries, in which incumbents often run away from party leaders to protect their ideological right flank.
