This really is an amusing comic.  There's not much depth to it but it's still very clever.  Evolution and creationism have always been topics of note especially with specific party affiliation.  Religious people tend to be more conservative so this comic is poking at conservatives for the most part.  The comic makes the joke that those who believe in creationism are the same people that actually have not evolved as much as others.  The artist uses the idea of evolution or lack of evolution to give the reason for people believing in creationism. 

Tres Mas

This comic is very self explanatory.  It shows Mitt Romney's hands shaking an etch-A-sketch which of course has a picture or Rick Santorum on it.  As Romney shakes the etch-A-sketch the image goes away.  This is very obviously signifying Santorum dropping out of the race.  It's interesting that the artist did choose to make Romney's hands holding the etch-A-sketch however.  It makes it seem like Mitt Romney is responsible for Santorum dropping out of the race which he actually indirectly is but it was still Santorum that made the decision.  It wasn't Romney that made that choice. 

This will only hurt a little

I like this cartoon a lot.  There really is a lot of meaning in this one picture.  There's Obama sitting in a doctors office symbolizing his health care plan, Obamacare, getting his reflexes checked.  His healthcare plan has recently been on trial so in the doctors office there are two judges with gavels getting ready to check the Reflexes of Obama. (Obamacare) The Liberal judge is tapping his knee with a small gavel similar to a the rubber hammer doctors use.  And the Conservative judge is about to smash Obama's knee with a gavel closer to a sledge hammer.  The message of this cartoon is to point out that Conservatives are trying to find flaws in Obamacare and really at any cost. 

Hold On Tight

 This is a fun comic to depict.  Initially, one might think that this is directly correlating to the republican primary in general.  However there's more to the photo than just that.  Rick Santorum at one point or another has talked of strapping his dog to the top of his car on a vacation.  This photo on the New Yorker then twists that idea and makes it so Mitt Romney has Santorum strapped to the top of his car like a dog.  The image can almost be looked at as Santorum is to his dog as Romney is to Santorum.

One or the Other

This is a hilarious comic that really makes a lot of sense.  It adds some humor to one of the largely talked about topics present in the Republican Primaries. Most conservatives are against the use of contraception such as birth control.  Most conservatives also dislike the idea of welfare.  Now "the PILL" is halting the birth of many children in an environment where they cannot be properly supported.  If the pill were to be taken away more of our tax payer dollars would be put towards welfare for the women who have the children and also the children themselves as they grow with little support.  So by conservatives opposing both welfare and contraception they are contradicting them selves in a way which was displayed here in a very comical manner.  

I like sunsets and long walks on the beach

This comic may look to be referencing the beginning of the republican primary race but when looking at it critically it can be inferred that it might be a microcosm for the race as a whole.  What's important to not of course are the flip flops that Mitt Romney is wearing at the starting block.  These shoes could have many different meanings.  One might look at this comic and say that the flip flops are referencing the frequent changing positions on social issues Romney has experienced in the past, hence "the flip-flops"  Another interpretation of these flip flops might be the extremely volatile public opinion towards the Republican candidates.  A different way of analyzing this might mean one to believe that the flip flops stand for Mitt Romney's inability to close out the race.  Flip flops obviously aren't good running shoes so there's a good chance they symbolize lack of closing ability.   

My ideals are People?!

This comic specifically focuses on two on the Republican candidates running in the Republican primary.  These would be Mitt Romney and Rick Santorum.  They are both holding signs which symbolize some of their supposed core beliefs.  Mitt Romney is holding a sign saying "Corporations are People!"and Santorum is holding one saying "Embryos are People!" as they question whether this girl standing in front of them, who represents the middle class is a person at all.  The comic is meant to highlight the lack of interest these candidates supposedly have in the actual majority of the U.S. citizens and their zealous advocacy towards supporting big business and pro-life.  The rest of the comic isn't that important in terms of having much meaning, it's just the punchline of the strip.
