No seat for Sam Stein, or other bloggers, in the daily briefing. From FiveThirtyEight.com:

I admire Sam Stein. The other day, we were in a Robert Gibbs briefing, and he sat down before it started in a seat that happened to be Politico’s. Having once been politely booted from the same seat by Jonathan Martin, I stood nearby curious to see how long Sam would make it. Sure enough, a few minutes into the briefing, Carol Lee came and kicked him out, asserting her right, as a member of that organization, to sit in the assigned seat. Politico’s seat in February was in the sixth row, far left, but it has now moved up to the fourth row, three seats behind CBS’ Chip Reid (see charts below).
Undaunted, Sam got up, noticed the second seat in the last row was empty, and re-seated himself. About five minutes later, Todd Gillman of the Dallas Morning News claimed it. Sam had to stand with the rest of us; Huffington Post, like FiveThirtyEight, doesn’t have a plaque-stamped seat.

Watch out, Helen.
