@Progress0nly: That's what 99+% of everyone who runs for office does. It's a business, and just like in business, it's about capitalizing on the fads and zeitgeist, reading the tea leaves to see what's coming down the pike, and hop on the train before everyone else does. Also, it's about jumping tracks if ahead looks unfavorable.
"My position has evolved."
"I was for it before I was against it."
"It's... more complex than we thought."
"I delved deeper and have changed my position."
blah blah
