I inferred from Rush Limbaugh that he's confident of the same; he doesn't know when, but the Dems "blow it" every time and it will happen again.

I believe it, too. When Obama became president, the Dems owned all the branches of government. Then when it seemed like they would reign for another forty years, they lost them (though in fairness there were a lot of RINO's around so it was more of a "lost on paper"). And they may have been cheating even back then, too.
