Sen. John McCain's choice of Alaska Gov. Sarah Palin as his vice presidential running mate has pushed Sen. Barack Obama into a corner in regard to Obama's campaign slogan: change.
Both Obama and his running mate, Sen. Joseph Biden, clearly are products of the liberal establishment in Washington. Even on the face of the ticket it is difficult to accept that the two will be agents of real change.
But McCain has a longstanding reputation as a maverick within the Republican Party. Palin, though newer to politics, also has a rebellious streak. As governor she has battled against her own party on important issues. She is bucking the party "establishment," and she has done so with a very strong hand.
And, like McCain, she is not easy to stereotype on other issues. Though she favors increased drilling for domestic oil, she also has pushed for higher state taxes on oil companies.
McCain chose wisely, for the simple reason that it will be much easier for voters to view his ticket as agents of change than it will be to believe promises made by Obama and Biden.
