There is no chance that Barack Obama will get more than 38% of the vote in Oklahoma this Election. If Obama does manage to get more than 38%, there is something wrong with the Oklahoma electorate. It goes against the electoral grain of wood in Oklahoma, if a liberal African-American Senator running for President of the United States manages to get more than 38%.
The first sentence of this post is fine. The second sentence says that the voters are wrong if they vote in a way their demographics don't suggest. The third sentence uses a massive mixed metaphor ("Electoral grain of wood?"), and makes a presumption about a circumstance that has never happened before (A "liberal" African-American Senator running for President).
