That has been on my mind. No, I don't think he could get his baggage through Congress, if that answers your question. I DO think he would shake things up, especially on these endless wars and erosion of privacy and freedom.
As for the gnashing of teeth about his so-called pro-life, anti-Israel, anti-gay, mumbo-jumbo, much or all of that is deflated if you take into account he's coming from a different direction. He says (if I remember correctly) that he's against same sex marriages. But then goes on to say, it should be left up to the states. And as far as being anti-gay, he has been boldly and repeatedly saying, in Iowa, that the government, at every level, should stay out of our bedrooms.
I think he's real. And I think he could make a difference in important areas, while being contained by Congress in others.
