The snows that obliterated Washington in the past week interfered with many scheduled meetings, but they did not prevent the delivery of one important political message: Take Sarah Palin seriously.

Her lengthy Saturday night keynote address to the National Tea Party Convention in Nashville and her debut on the Sunday morning talk show circuit with Fox News' Chris Wallace showed off a public figure at the top of her game -- a politician who knows who she is and how to sell herself, even with notes on her palm.

Blessed with an enthusiastic audience of conservative activists, Palin used the Tea Party gathering and coverage on the cable networks to display the full repertoire she possesses, touching on national security, economics, fiscal and social policy, and every other area where she could draw a contrast with Barack Obama and point up what Republicans see as vulnerabilities in Washington.

Her invocation of "conservative principles and common-sense solutions" was perfectly conventional. What stood out in the eyes of TV-watching pols of both parties was the skill with which she drew a self-portrait that fit not just the wishes of the immediate audience but the mood of a significant slice of the broader electorate.

Palin did not wear well in the last campaign, especially in the suburbs where populism has a limited appeal. But when Wallace asked her about resigning the governorship with 17 months left in her term and whether she let her opponents drive her from office, she said, "Hell, no."

Those who want to stop her will need more ammunition than deriding her habit of writing on her hand. The lady is good.

WALLACE: What do you think of Barack Obama's presidency so far?

PALIN: He has some misguided decisions that he is making that he is expecting us to just kind of sit down and shut up and accept, and many of us are not going to sit down and shut up. We're going to say no, we do not like this...

WALLACE: Wait, wait, where's he saying sit down and shut up?

PALIN: In a general just kind of general persona I think that he has when he's up there at, I'll call it a lectern. When he is up there and he is telling us basically, I know best, my people here in the White House know best, and we are going to tell you that yes, you do want this essentially nationalized health care system and we're saying, no, we don't. And the messages are not being received by Barack Obama. So I think instead of lecturing, he needs to stop and he needs to listen on health care issues. On national security, this perceived lackadaisical approach that he has to dealing with the terrorists. We're saying that concerns us and we're going to speak up about it and please don't allow this persona to continue where you do try to make us feel like we need to just sit down, shut up and accept what you're doing to us.
