Why do you think that? Libertarians usually only get 2% of the vote!
I think the left will literally do whatever they can to destroy her credibility, as evidenced by their incessant obsession with her, hit pieces in Vanity Fair, which curiously has no "on the record" sources!
Let me clue you in on some logistics... 60% of the country is Conservative, and 95% of the country believes in something greater than self. The so-called "religious right" is a very powerful voting block, that is why you saw Al Gore and John Kerry visiting black churches and singing with the congregation, when they were campaigning... it's why Bill Clinton carried that Bible under his arm through the Lewenski ordeal. Even pinheads understand they must appeal to the religious people of America, or their goose is cooked.
If you want to know what happens when a politician doesn't project a strong voice for the religious right, ask John McCain! He spent the majority of his campaign, taking the Damo approach, and avoiding controversial issues held by the religious right, not wanting to be seen with anyone from the religious right, refusing to appear in public with them, and tap dancing around questions with canned statements of platitude, which came off sounding as if they were things his handlers told him he had to say, not what he truly felt. Even when it came to the issue of abortion, McCain responded with a standardized version of what any right-wing politician has to say, and that was it. I was actually shocked he came out against abortion and nominated Sarah Palin. But again, McCain just didn't seem to have conviction.... it was as if he were saying what he though he had to, and nominated who he thought he needed to win. I think the 'religious right' saw through his phoniness and stayed at home.
