I don't think it really matters who he picks. It is pretty obvious that he is going to lose. I don't even care for Obama. I see very little chance in Romney winning.  I suppose I will vote one more time in the USA before I throw in the towel.  My vote goes to Gary Johnson.

People have to remember too that Romney is really not generating much excitement in the "conservative" realms of the party. Many Libertarians are not fond of him at all either. he almost needs someone who would have the ability to draw from both groups. In this election Romney has to generate more excitement if he really wants to win. I also think he needs interest from more Libertarian leaning voters. a decent number of Libertarians will not support his ticket no matter what. But I think someone like Rand Paul could draw some of them over.

Romney has similar problems to Obama right now. Obama has no where near the electric fainting fever that so many voters had for him in 2008. He ran on the whole "hope and change" slogan and instead all we have had is class warfare rhetoric, ugly chicago style politics, intense division in washington, race bating, an extremely long period of high unemployment, the blame game, a health care law that wasn't wanted but rammed through anyway, and huge increasing budget deficits. Obama is not well liked either.

....in other words get ready for a very ugly negative presidential campaigns on who will be worse as president.

That is true. His style tends to be geared to more tested politicians, and the "safe option". in 2008 Mccain tried the "Surprise Out of the Box" approach with Palin. While it generated a lot of excitement in a lot of "conservative groups" and conservative talk radio he still lost big. I don't think anyone could have stopped Obama at that point. Especially since Obama was giving Chris Mathews a "tingling sessassion up his leg".

If Romney wants to win I don't see him have much chance if he picks someone like himself that has been in the public spotlight as a politician. In order to win he has to generate some kind of excitement. He as himself will not generate enough to win unless "Just get Obama Out" croud is large enough which is possible but I don't see it yet. The way it is now Obama's base will go out and vote for him in droves no matter what he is done. The "Get Obama out" crowd will vote for anyone but Obama. That leaves a lot of "on the fence/mushy" independant type voters getting fed up with the ugly campaigns that will transpire and many will just get fed up and stay home. Thats what Obama wants. If that happens Obama wins.

Hopefully he's not one of those screaming anti-Castro Cuban-Americans, though i've never looked into his background. The last thing our foreign policy needs is someone who's just going to stump for keeping that pointless embargo up (Cuba would be democratic now if it weren't for the embargo, which is kept in place almost entirely by screaming Cuban-American immigrants)

He should pick Rand Paul, that's my first choice.

If you're asking whom he should choose in order to attract independents and conservative Democrats, I would say Joe Lieberman. It would be extremely, almost impossibly difficult for the Obama campaign to dig up any dirt or throw any mud at Lieberman, there would be too much backlash. His reputation for being a nice guy, a centrist, and having a cool head precedes him.

That would actually be a strategically good choice. Worse it could do is piss off the far right even more than they already are, but who are they going to vote for?

They will click on the vote for all Republicans.  Party line voting is the best way to vote!  Don't even have to do any research on candidates. 

I like your idea about Joe Lieberman though.  It would make the next few months of watching Jon Stewart on the Daily Show awesome.  He does one of the best Joe Lieberman impersonations.

Im not so sure. Pissing off an already pissed off and fired up base would have some interesting outcomes.

Trust me there would be a 60% chance that a small 3rd party would arise. Whether it would be more libertarian leaning or more social conservative type leaning group is hard to say. There are some people that are so very strict with how they vote that they would refuse to vote for a ticket that included lieberman. Many of those people are more socially conservative types like Pro-Life. Im almost certain if Lieberman was the running mate you would have at least 5 to 8% of the republican base voting for a 3rd party ticket. Some people are just that strict in their voting.

A few days ago I would have disagreed with you and said Christie would be a poor choice.  However, a few days ago on the Daily Paul blog I saw a video that intrigued me.  Christie was arguing for the abolishment of the War on Drugs, and calling for the release and treatment of all non-violent drug-related offenders.  Which is something I strongly believe would be in our best interest as a compassionate society.  It surprised me because most Republicans, especially with national fame, wouldn't be caught dead speaking the truth about the War on Drugs.   So, I have to say, I would be fine with Christie too. 

Bill Maher ofcourse.
