Very upset to learn one of my esteemed predecessors in this space, MoJo’s Kevin Drum, has had to be hospitalized with a back and/or bone ailment. Here’s hoping and praying Kevin gets well quickly.

Here are some midday items in the chafing dishes:

* As situation in Ottawa begins to emerge from mist, one shooter killed inside Parliament Building by sergeant-at-arms, a Canadian soldier killed at nearby memorial, at least one additional injury, and at least one shooter still abroad.

* TPM’s Sahil Kapur discusses fears among MA Dems that Martha Coakley about to lose another unlosable statewide election.

* Matt Baretto argues CO polls are getting Latino vote wrong much like NV polls did when they predicted Sharron Angle win over Harry Reid in 2010.

* Thom Tillis appears to waffle on prior opposition to Medicaid expansion, which is a counter-signal to Mike Pence’s apparent waffle in the opposite direction.

* Now you can read the “annotated version” of the “Palin Brawl Police Tapes” by TPM’s Ahiza Garcia.

And in non-political news:

* University of Georgia ends Todd Gurley investigation, seeks NCAA clearance for him to play, which they are expected to get.

As we break for lunch, here’s more Dory Previn, with a song about Janis Joplin: “A Stone For Bessie Smith.”
