We must be cautious, however ! Presently, the lamestream media is shouting the slogan, "throw the bums out". They are saying that the public has an "anti-incumbent" thing going. Above all, don't fall for that line !
The liberals know they are in for a whipping this fall..but they also know that if they can convince a sufficient number of conservatives and right leaning moderates to abandon their own, regardless how these people voted upon the issues...they stand a chance of holding power.
First off, we can never implicitly believe anything a liberal says (e.g. " I did not have sex..."), and secondly we know that the same fanatics who supported Obama, will vote in a block for anyone he tells them to support. Ends up, mostly the more conservative office holders will be tossed under the bus.
Instead, we should vote more intelligently..do our research..and if we find an officeholder who has voted with the liberals too often..throw him/her out!
... On the other hand, if your rep has voted conservative for the very great majority of issues, don't throw him/her out..because you may be putting a radical leftie in his/her place.
