No. Mitt looks like he's acting. Like he acted like a liberal to get elected as governor. Now he is acting conservative to get elected as president. Mitt doesn't come across as real. Fred comes across as genuine. My take is Mitt probably is conservative, but who knows. He appears to be the type to say what he thinks will get him elected.
Now that's funny! You are dinging Romney for "looking like he's acting [presidential]", but admire Thompson for coming across as genuine, when he was actually being paid to act Presidential.
