On the contrary, you are living in a fantasy world. With Obama, it was "Hope and change." With Romney, it's "Hope he'll change."
We know how the first one worked out.
You can vote for the GOP version of the same -- just remember that if your bastard wins, you will GET WHAT YOU VOTED FOR.
Me, I'm voting to weaken whichever bastard wins, Romney or Obama. I'm voting for a popular vote plurality. I'm voting third party -- because unlike you, I understand that there is no such thing as voting "against" -- you can only vote FOR something. You're voting for more liberalism; I'm voting for putting liberalism on defense.
If Romney wins, I predict the greatest case of buyer's remorse in political history. It will make the liberals' disappointment in Obama look like child's play.
As Romney walks back every one of his campaign promises, it will be hard not to say "I told you so." This process which has already started will accelerate if Romney wins. Here's what I think will happen: Romney's history suggests that he doesn't want conservatives - he'll just use us if he can. Once elected, Romney will run to the left where his political philosophy resides and then form a left-of-center coalition with the Democrats and RINOs. Angering conservatives will play right into the great reconciler role that Romney wants to play. He and his people will point to conservative opposition to bolster his claim to occupy the reasonable middle and his claim to political courage in fighting the Radical Right. In terms of partisanship, Mitt Romney reaching across the aisle will make John McCain look like Rush Limbaugh in comparison.
And the only way your vote "to weaken liberalism" will ever be noticed is if it actually gives Obama another 4 years.
