From the Washington Post:
Ohio Gov. John Kasich, who has been actively gauging reactions to a possible campaign for president in 2016, is now moving rapidly to assemble the staff and financial resources for such a bid and is looking to declare his candidacy sometime after June 30, according to knowledgeable Republicans.
Kasich advisers say his principal competition would come from former Florida Gov. Jeb Bush, Wisconsin Gov. Scott Walker and Sen. Marco Rubio (Fla.).
Kasich v. Bush
"They consider Bush potentially hobbled by resistance to a third president from the same family," reports Post. Asked in the recent interview whether his message would be similar to Bush's, Kasich said, "I don't know anything about [Bush's theme]. I really don't. I've never listened to him. What's "Right to Rise"? Getting up in the morning?" Right to Rise is the name of Bush's super PAC.
Kasich v. Rubio
Kasich advisers view Rubio as having significant potential but faced with the problem of being a first-term senator who would be trying to follow a first-term senator -- President Barack Obama -- to the White House. "We hired an inexperienced person to run the country," a Kasich adviser said. "That didn't work out very well. That plays well in his [Kasich's] favor."
