A charitable campaign focusing on the atrocities of a third-world warlord was able to so comprehensively take over social media on one of the most critical days in the country's political calendar.

From Donald Trump to Newt Gingrich's moon colony, the Republicans that have left their mark on the 2012 primaries bear an uncanny resemblance to the quirky gaggle of dinner guests in Dinner for Schmucks.

To Newt, bless his heart: three wives, two religions, and one moon colony later, I'm not sure "tortoise" is the choice I would have gone with to describe myself, but okay, tortoise it is. Best of luck to you.

The equivalent of 0.000351% of the population of the United States (or just 35 of every 10 million Americans) has given 96% of the money determining who stays and who goes in the Republican primary.

Republican women may have flirted with Rick Santorum, but they're now less interested in going all the way. In the early contests, Santorum did better with women than with men. Now, his early strength with women has become a weakness.

Had Romney or Santorum won Ohio by a landslide vote, the winner could have made the case that he is the best candidate to take on Obama. But that argument, for Romney, is becoming harder to win.

As GOP primary voters lurch from Santorum to Romney to Gingrich to Paul and back again, one thing is clear: the Republican party is undergoing a seismic shift in consciousness whose appeal to the American people is increasingly dubious.

Once upon a time, in what seems now to have been many, many Republican presidential debates ago, Florida GOP Senator Marco Rubio was king of the hill.

Every candidate had something they could claim as a positive on Super Tuesday. The contest for the nomination isn't over -- which is good news for voters in remaining states wanting to help pick their party's nominee.

Romney can come close to obtaining the necessary delegates, but may not reach it, continuing speculation of a possible brokered convention. Might there be a white knight to rescue the party?

Tuesday elections are unrealistic and burdensome in today's hyperactive workweek. Americans are busy. Finding the extra time to vote mid-week is difficult for everyone and practically prohibitive for many working class citizens clocking long hours at work while looking after a family.

For the Republican Party to be attractive again to the various groups that have historically found a home under the "Big Tent," it needs to think big and put forward a new generation of bold ideas that fit neatly within the overarching themes of Republican values.

Today, voters in ten states will voice their preferences in the GOP's presidential nomination battle. But this year, the so-called Super Tuesday primary is shaping up to be just another act in the new blockbuster, Attack of the Super PACs.

Watching my parents mark their ballots, knowing they never skipped an election, instilled in me a belief that it was a privilege to be able to vote but also that it meant something.
