"Daniels is the adult in the room saying the party is over, it’s time to clean house"

A Daniels candidacy probably would be taken as a sign that the games are over for the Republican Party, that it is time to buckle down and organize to beat President Obama.

“He will turn a race that is about less serious politics into a race about more serious policy,” argued Alex Castellanos, a Republican media consultant who is not aligned with any candidate heading into 2012. “Daniels is the adult in the room saying the party is over, it’s time to clean house. That contrast in maturity is how a Republican beats Obama.”

The president has acknowledged as much about Daniels, telling an Indiana television station that the governor is “a serious person” before adding: “I have some significant philosophical differences with him.”
