* Meeting in The Hague, President Obama and the leaders of allied countries have effectively kicked Russia out of the G-8, at least for the moment, by cancelling an upcoming meeting in Sochi and scheduling a new one, to which Russia will not be invited, in Brussels.

*The Affordable Care Act will be an issue in pretty much every Senate race this year. In Michigan, Republican candidate Terry Land wants to completely repeal the law, but won’t say whether she supports the expansion of Medicaid, which governor Rick Snyder, a Republican himself, accepted.

“Obamacare does not work,” she said today. “I applaud Gov. Snyder for doing what’s best for Michigan families while complying with the federal mandate.” No one could quite figure out what that meant.

* But maybe she just hasn’t thought about it. If so, she’s not the only one. Greg reported this afternoon that Scott Brown’s position on the Medicaid expansion remains uncertain, and Ed Kilgore is flabbergasted. “How on earth can this man — or any other Republican running for the U.S. Senate from sea to shining sea — not have a position on the Obamacare Medicaid expansion before they announce?”

* Drew Altman, the head of the Kaiser Family Foundation, explains why many of the numbers dominating the current debate over the ACA — the number of people enrolled, the proportion of young people — are irrelevant at best. “Anybody willing to wait for a judgment based on the right metrics?” he asks. We’re going to guess the answer is No.

* The L.A. Times’ Michael Hiltzik wonders why nobody is telling the stories of people who have already benefited from the ACA, so he tells a few.

* Those Koch brothers sure are everywhere. I wrote about what function they’re serving for liberals, while here is a good example of how a Democrat — in this case, North Carolina senator Kay Hagan — is trying to turn the Kochs’ support against her opponent.

* Kentucky Democratic candidate Alison Lundergan Grimes rolls out what is sure to be a major theme of her campaign, that Mitch McConnell is the “senator of yesterday.” Which, given how all-out nasty that race will inevitably get as we approach November, is kind of sweet and poetic.

* According to a report by Stephanie Simon in Politico:

Taxpayers in 14 states will bankroll nearly $1 billion this year in tuition for private schools, including hundreds of religious schools that teach Earth is less than 10,000 years old, Adam and Eve strolled the garden with dinosaurs, and much of modern biology, geology and cosmology is a web of lies.

Pre-release publicity has not specified whether Russell Crowe rides a triceratops on the deck of the ark in the upcoming film “Noah.”

* As you know, Nate Silver says Republicans are a slight favorite to win back the Senate this fall. See Jonathan Bernstein on what Silver’s projections actually found, and Steve Benen for some important perspective.

* If you missed David Fahrenthold’s amazing story over the weekend about the office where they process federal government employees’ retirement papers — underground in what used to be a limestone mine in Pennsylvania, using technology that three decades ago was derided as outdated — you really should read it. Key nugget:

 The employees here pass thousands of case files from cavern to cavern and then key in retirees’ personal data, one line at a time. They work underground not for secrecy but for space. The old mine’s tunnels have room for more than 28,000 file cabinets of paper records.

* If you are no longer in your twenties and want to make it in Silicon Valley, the tech industry has a message for you: Take a hike, grandpa. The New Republic’s Noam Scheiber documents the Valley’s brutal ageism.

* And finally, “Fast and Furious 7,” a movie that has not yet started filming, will still feature the late Paul Walker. So they’ll recreate him with a combination of body doubles and CGI, which is not at all creepy and weird.
