Just razzle-dazzle the voters with lies.
If you're trying to destroy Medicare, say the Democrats are trying to destroy Medicare. If you're raising taxes on the middle class while giving their money to the rich, say the Democrats are bankrupting the country and that rich people deserve everybody else's money because they're "job creators."
Whatever evil you're up to, claim it's the Democrats that are up to it. Claim Romney and Ryan have the same budget. Then say they have different budgets. Then repeat that they have the same budget.
On talk shows drown out the truth by talking over it so that Democrats can't be heard. Just razzle-dazzle 'em.
