A PRESUMPTUOUS CELEBRITY…. Yesterday, in the midst of a speech, Sarah Palin told voters about what they could expect from a “Palin and McCain administration.” Seriously, there’s video of it.

What’s more, ABC News’ Jake Tapper added that he’s heard Palin refer to John McCain as her “running mate,” a designation Tapper said he’s never heard a “VP nominee use when discussing the guy at the top of the ticket.”

And just to add insult to injury, Jonathan Martin reports that twice this week, he’s noticed a fair number of people leave campaign rallies after Palin speaks, not sticking around long enough to hear what John McCain has to say. It happened on Tuesday in Ohio, and again yesterday in Iowa.

“I look up, about five minutes into McCain’s address and see a steady stream of people walking out of the rally,” Radio Iowa’s Kay Henderson reported from a McCain-Palin event in Cedar Rapids.

Taking these developments together, the two words that come to mind are “presumptuous” and “celebrity.” Now, if I could only figure out why those two words seem so familiar….
