We covered a fair amount of ground over the weekend. Here’s a quick overview of what you may have missed.

On Sunday, we talked about:

* Mitt Romney looks like he’s caving on tax returns, but there’s a catch: he’ll only disclose materials going back to 2010.

* With the eyes of the political world on Florida for the next nine days, which Republican presidential hopeful has the edge in the Sunshine State?

* How did Gingrich excel in South Carolina? The exit polls tell us quite a bit.

* A week ago, the race for the Republican presidential nomination had the benefit of simplicity. After Saturday’s South Carolina primary, it’s a lot more complicated.

And on Saturday, we talked about:

* Romney may have a problem that’s just tough to fix: the more people see him, the more unfavorable their opinions of him.

* The entire GOP presidential field simply prefers to pretend that George W. Bush doesn’t exist. There’s no reason for the rest of us to go along.

* We’re occasionally reminded that Mike Huckaee, for all of his alleged jovial charm, has a deeply ugly edge to his personality.

* In “This Week in God,” we covered, among other things, the fact that the religious right movement keeps striking out every time they try to pick the Republican Party’s presidential nominee.

* With Gingrich excelling thanks to strong debate performances, will Romney take a gamble and start avoiding debates?

* It wouldn’t be a South Carolina Republican presidential primary unless there were some nasty, anonymous smear campaigns.

* And I was on MSNBC’s “The Ed Show” on Friday night, so I posted the clips.
