Do you know what the GOP message really is? If you look at what they do and the candidates they nominate, you will see that the GOP message can be summed up in a few slogans:
The GOP -- Bankrupting the nation at a slightly slower pace than the Democrats!
The GOP -- Huge government at a slightly lower price.
The GOP -- Dedicated to trampling the Constitution in the name of "national security".
The GOP doesn't have a "messaging problem". It has a "principle problem".
