“find that conservative presidential candidate that conservatives could all unite behind”
One has yet to be born.
Jesus is not a politician.
Well, barring the second coming of Ronald Reagan, I tend to agree with you.
But.. I think we could say we were united behind GWB.
This time though, there is no unity except we strongly prefer NotMitt.
However, you can't run nobody against somebody and until there is unity behind somebody... nothing changes.
And this is where we are right now, still.
