Good points. I really don't know much about either. Looking at the swing states, if the Republicans can pull even a relatively small portion of Latino vote from Obama it could make the difference. To get the swing they must appeal to the middle as they must do to win with any other ethnic group. To do this however will lose Romney some support from the Republican "base". Romney is already considered too moderate for Tea Party and religious conservatives so selecting a moderate Latino VP is the way to go. No matter who he picks, the right will cast a vote for Romney simply because they are obsessed with getting rid of Obama.
Way too early for predictions but if Republican strategy doesn't have an element of eating into Obama's lead in minority votes, they will lose. Romney gets the popular majority and Obama wins electoral vote.
