no, she didn't. she was a hail mary by the mccain campaign that didn't pan out, sure, but there was no republican presidential candidate, especially no gop vice presidential pick, who was beating barack obama in 2008. the economic crash two months before the election plus george w. bush having like a 25% job approval rating (lowest in the history of polling)... the gop was just way too toxic that year. only way they won is if obama himself fucked it up, nothing their nominee could have done would have changed the outcome.
