By all means, keep making up stuff about Mitt Romney.
But the best thing to do is to lie about President Obama himself.
Get back to the classics: Cash for Clunkers, Solyndra, auto bailouts, Dodd-Frank, ObamaCare, all raging successes.
And the best of all: President Obama saved us from another Great Depression.
Do not defend yourself against these. Just say them, and pound them home.
