(CNN) – Sarah Palin has learned a lot about politics this midterm election season and now she's advising fellow conservatives on how to avoid a few of the perilous pitfalls that beset some of the candidates she backed in 2010.
In a column for the National Review, the former Alaska governor lays out several "lessons" of the 2010 campaign, including the need to "fight back the lies immediately and consistently."
Referencing the Alaska Senate race, where the former governor endorsed Republican Joe Miller over incumbent GOP Sen. Lisa Murkowski, Palin suggests Miller all too easily allowed himself to be defined by the opposition.
"Some candidates assumed that, once they received their party's nomination, the conservative message would automatically carry the day," she writes. "Unfortunately, political contests aren't always about truth and justice. Powerful vested interests will combine to keep bad candidates in place and good candidates out of office."
Miller beat Murkowski in the primary but appears to trail the incumbent senator in the general election vote count after Murkowski ran an aggressive campaign as a write-in.
Palin is also warning future conservative candidates not to tempter their rhetoric in such a way to avoid labels of "extremism."
"If candidates are going to talk boldly on the campaign trail about entitlement reform and reducing the size of government, they must be prepared to word it in such a way as to minimize the inevitable fear-mongering accusations of 'extremism,'" Palin writes. "We are quickly approaching a fiscal turning point where these crucial reform discussions will be mandatory. We need to speak about them in a way that the public will embrace."
Though refraining from offering any hints at her own political future, Palin also makes clear she plans to play a key role in GOP's 2012 efforts.
"In 2012, we need to renew our optimistic, pioneering spirit, revive our free-market system, and restore constitutional limits and our standing in the world as the abiding beacon of freedom," she said.
