This is a very lively argument. Vote Mitt, vote a spoiler/protest, vote nothing (virtually nobody is saying vote Obama). If Mitt were to keep all his current campaign promises it would be very little to worry. But Mitt waffles and Mitt has been very leftist (like the first implementer of gaaaaay ‘marriage’). Of course Obama will never ever accuse Mitt of being too leftist.
The only negative is the Dems have a campaign against him already.
So did REAGAN, if you recall. It’s why Conservatives demanded he pick a conservative, like Dan Quail, as VP.
If Mitt is a waffler, Obama is a confirmed radical leftwing socialist. With Mitt, there is at least some hope he can be pressured into a few conservative agenda items. With Obama it will be big fat ZERO.
Note to all purists: Do not cut off your nose to spite the ears.
Mitt’s predecessor in MA, Gov Paul Celucci (R-ino) - he was the one who nominated a woman from South Africa to be Chief Justice of the SJC in MA. Hers was the deciding vote (4-3) to legalize gay marriage in MA.
