Trey Grayson, the GOP hand-picked successor of Sen. Jim Bunning, is an indication that the party leadership had better take a harder look at the candidates they field from now on.

It should be painfully obvious to them by now that running candidates who walk away from any semblance of conservative principles by favoring the expansion of the federal government (i.e. GWB) or waffling on issues (i.e. McCain), is a sure-fire way to give the democrats a guaranteed win in any race they run.

Doing the same thing over and over again, expecting a different result is an definition of what?
