U.S. Sen. Ed Markey can brag all he wants about how his huge win yesterday was a “testament to the power of the progressive movement.” That may be true in his Dem primary race. But not so true in most other state races yesterday, as old-time Dem incumbents like Steve Lynch and Richard Neal beat back progressive challengers. Even a young-one establishment type brushed aside progressives/socialists yesterday to easily win in the 6^th Congressional (see Dan Koh below). All in all, there was no huge generational/ideological shift last night in Mass., keeping the state deep blue as opposed to loony left. The AARP Establishment held.

Here’s a few other post-primary thoughts:

— Polling accuracy, for a change — After major polling screw ups in Wisconsin and Michigan, the polls were right on target in the U.S. Senate and GOP gubernatorial contests yesterday in Mass. – to Seth Moulton’s chagrin. The NYT’s Reid Epstein noticed the same thing.

— Wu’s mixed power messages – The mayor wanted to send a message to local Dems in yesterday’s primaries: don’t cross me on key issues on Beacon Hill. But her Trump-like  dominance strategy didn’t work so well yesterday, as state Sen. Nick Collins easily fended off a Wu-backed challenger.

Yet, state Sen. Bill Brownsberger, another Dem targeted by Wu, was in a too-close-to-call race as of this morning. Whether Brownsberger wins or loses, Wu did put a scare into him, serving notice to other would-be Dem defiers that she can at least make life miserable for them come election time. … The Globe’s James Pindell agrees: Wu lost but also won.

— Dan Koh, New Establishment – Dan Koh’s long quest to become a full-time politician finally succeeded yesterday in the 6^th Congressional race, thanks partly to uber-establishment help from the likes of Joe Biden, Kamala Harris, Marty Walsh etc. Koh’s classic student-government-type resume practically shouts establishment — Phillips Academy, Harvard University, White House aide, etc.

— Rachael Rollins: maybe next time – Rachael Rollins’s comeback effort failed yesterday, as incumbent Kevin Hayden somewhat easily won the Dem race for Suffolk DA. But remember: Rollins isn’t the type to simply fade away, even if voters tell her to go away. Unfortunately, she’ll probably be back. State legislature? 

— Neal’s lucky win – The DUI leak hurt Jeromie Whalen. Perhap not a lot. But probably enough to make a close race against Richard Neal only a somewhat close race yesterday. Neal was lucky. Or was it just old-fashioned hardball politics that gave him the edge?
