Why I Can't Stand Most Politicians but Especially Romney

"Romney began his political career as a pro-choicer. In the story he tells, he had an epiphany, a flash of insight, and committed himself thereafter to protecting life. But that isn’t what happened. The real story of Romney’s conversion—a series of tentative, equivocal, and confused shifts, accompanied by a constant rewriting of his past—paints a more accurate picture of who he is. Romney has complex views and a talent for framing them either way, depending on his audience. He values truth, so he makes sure there’s an element of it in everything he says. He can’t stand to break his promises, so he reinterprets them." - William Saletan

I guess I can't figure out why people who enter politics can't just honestly represent what they represent and get elected or not because of that instead of shapeshifting their beliefs to cater to whomever will elect them at the expense of the truth.
