I watched Joe Bluhm (http://joebluhm.blogspot.com/) do a dog caricature on UTube. I was also inspired by the way Wallace Tripp does animal cartoons.

Can't forget 'ol Mitt.  He's getting more colorful too.

Newt becomes even more colorful

Taking a break from drawing a face allows you to see it more clearly when you come back to it.  Meanwhile, more practice drawing cutesy cartoon girls.

Politics always provides ample opportunity for caricature.  Currently, the focus seems to be shifting to Newt.
