Notice also the "elephant" in the room......look who are the folks surging in the GOP polls.....the NON-politicians, Trump, Carson, and Fiornia. This is how so aliented the GOP has made its voting base....the ongoing pledges to reign in Government, the Democrats, and Obama, only to see them drop right back in line with the poltical estabishment, once they've been sworn in......outside of a few exceptions of course.
The polls demonstrate that the electorate is having a hard time swallowing what the professional Politicians keep promising, given their track record of dropping any effort, as soon as the 1st line of resistance is felt from the left or MSM. So, who better to throw their polling support behind than some folks who aren't professional politicians. I still think a Walker/Rubio ticket is the bees knees, but I completely understand the anger that's fuleing the polling successes of folks like Trump, Carson, & Fiorina
