Tax cuts to stimulate the economy and increase Federal revenue worked under Kennedy. Worked under Reagan (though, with Reagan, the effect was rather spoiled by a massive increase of federal spending.)

There's reason to think it can work again, though I am dubious about the "rebate" format.

I would think even a Democrat could come to terms with this, especially when I cite the Holy Name Kennedy - who, in retrospect, is so far to the right of most modern Democrats that he'd be considered a conservative.
