Have you caught your breath after Super Tuesday? What a night.

So what do we know after the dust has cleared? Well, as expected, Republican John McCain took a commanding lead in the delegate count, thanks to wins primarily on the East Coast and California. Overall, including Tuesday’s races, he’s picked up 570 delegates on the way to the required 1,191 to secure the GOP nomination.

Republican Mike Huckabee performed well in the South, where he connected with evangelical voters. Huckabee didn’t have a win in over a month, but Super Tuesday showed that he’s still a force.

Republican Mitt Romney scored some victories, but really needed to win delegate-rich California. Still, Romney has a total of 251 delegates to Huckabee’s 175.

But McCain looks to be well on his way to securing the nomination.

The Democratic side is a lot more interesting, after Hillary Clinton and Barack Obama traded victories in what is shaping up as a classic battle for the nomination.

Clinton now has 760 delegates, to 693 for Obama. A nominee on the Democratic side needs 2,025 delegates.

As I've said in previous posts, it’s looking more and more like Pennsylvania will have a big say on the Democratic side when we get around to voting April 22.

Expect a huge amount of attention. There are no scheduled primaries or caucuses after Mississippi’s primary on March 11. That’s six weeks that the candidates can spend in Pennsylvania.
