Bob Cesca hammers home the point:
Everyone with a realistic view of the the Obama administration knows what's what — for better or worse. At this stage in the proceedings, with another pivotal election around the corner, there's nothing wrong (and everything right) with making a strong case, without apologies, for re-electing the chief executive who's responsible for all of those better items on the list. And there are many.
The reasons for distrusting Obama are also many - his administration has fallen way short of its promise and his list of failures in key areas like banking reform and the environment are unforgivable. But there are accomplishments to be proud of (see Bob's link) and the alternative is so horrifying it is not worth contemplating doing anything to undermine his chances at reelection.
