Cultivating a Reputation for Incompetence.

A recipe for defeating Republicans in this amusing picture of the Tories flaying around waving their arms, hooting like a bunch of loons, lying and stumbling and pissing everyone off royally.  Which suggested a political tactic.

A lot of people who are not ordinarily political sociopaths are persuaded of Republicans' competence, regardless of evidence, which is a mental picture we tend to paint on the apparently wealthy and successful. Incidentally, this is why people buy expensive suits.

So to the entirely rhetorical and wholly politically point: don't attack their lack of compassion, or the ideology of greed, habitual prevarication, religious fanaticism, or even the increasingly naked racism. 

Attack their aura of competence. 

The last decade, we tend to assume, would have made that obvious. But it isn't- it has to be a constant refrain: Republicans are incompetent: butterfingered botchers and bird-brained bunglers. The Party of Can't and Wouldn't Know How.  The Heckuva Job party.

If I've learned one thing from the GOP over the years (and it was only one), attack your opponent's perceived strength repeatedly, repeatedly, repeatedly, until you are long sick of the sound of your own voice, and keep at it when they are down and at their weakest.
