If you're a US citizen, and
haven't been living under a rock, spending time in a cryogenic deep-freeze, or been held in the attic of a hot Oregonian girl's house

(or vice-versa) for several months now, the joke should be obvious.
"Would you vote for someone who doesn't know whether he's coming or going, first adopting a position and then rebuking it when the political sands shift? Do you want a ruler who's on record holding two mutually exclusive positions? If you've read my opponent's, Jesus H. Christ's, campaign manifesto, you're no doubt aware of his many flip-flops. The book is full of contradictions and weaseling from the very first page! Do you still think he has the integrity or perseverance to lead us in this time of crisis? I'm Bill Z. Bub, and I approved this message."
God faces renewed "flip-flopping" attacks
*Insert appropriately creepy evil laugh here*
