How soon before gas prices start to rise?

Yeah, it took a moment to kick in mentally. One day (Tues) it was $1.99 (and had been for several weeks) and then shot up to $2.09 by this afternoon. I'm scratching my head knowing the recent reports of continued drops in oil prices even with OPEC threatening to cull back production. Then the light flickered on and I realized what had happen...the elections were over.
