Why conservatives (and Republicans) should be against Romney

This may be like preaching to the choir, but here goes...

• Although Romney may be facile in debates and avoiding his weaknesses, this will not be enough to defeat Obama.  Obama will have hundreds of millions, if not a billion dollar war chest.  Obama will overwhelm Romney.
• Does Romney have weaknesses?  Yes.  It was evident in his failure to understand a question and he misspoke.  He admitted that.  But this is not an isolated incident.  Even establishment Republicans worry about his gaffes.  His narrow victory in his home state of Michigan was not entirely inspiring.
• About the inspiration aspect...  He doesn't get out the vote.  He would need every vote he can get against the Obama machine, but he routinely fails to deliver it.
• He has some ties to the Bush camp... Papa Bush endorsed him.  Obama could say that he's just another Bush.   The Bushes hold a grudge against Gingrich for his lack of support for the Bush tax hike of 1990.  George W Bush didn't invite Gingrich to speak at the 2000 Republican Convention.  It was a snub.  If Gingrich was right about his help being needed to defeat Dukakis in 1988, the grudge may have helped Clinton defeat Papa Bush in 1992.  That grudge should not allowed to help Obama win in 2012.
• Romney has not run an issues based campaign.  Instead, he attacks other Republicans who manage to get to front runner status.  A negative campaign against Obama will backfire.  Instead, the nominee should run an issues based campaign which Gingrich is advocating.  The nominee will not have Obama's war chest at his disposal.  Romney's won't be big enough.  What worked against underfunded Republican opponents won't work against Obama.  But Romney seems to be incapable of running an issues based campaign.
