Cruz: Reputation as a hotheaded upstart, also part of his appeal. Polarizing within his party. Also comes with birther baggage: Questions have been raised in some quarters about his constitutional standing to become president because of his birth in Canada, to a Cuban father and American mother. Deflection: Promised last summer to renounce Canadian citizenship but hasn't.
Jindal: Ambitious plan to replace state's personal and corporate taxes with higher sales taxes flopped, delivered dud of a speech when given juicy platform of responding to Obama's first presidential address to Congress in 2009. Deflection: Poking fun at himself. Jindal administration's award of a $200 million Medicaid contract is under investigation by state and federal grand juries.
Paul: Dear old dad: Must move beyond Ron Paul's fringe reputation. Bridge-burning in Congress endears him to tea party, could bite him otherwise. Deflection: GOP outreach to minorities. The Washington Times canceled his column after he was found to have used passages from other people in his speeches and writings as if they were his own. Deflection: Promising proper citations and footnotes for his pronouncements "if it will make people leave me the hell alone."
Perry: "Oops!" Memories of his stumbling 2012 campaign, a quick progression from a front-runner to flameout. Deflection: Owns up to his "botched efforts" in last campaign. Also a potential drag: a grand jury investigation in Austin into whether he abused power by cutting off state financing for an office of public corruption prosecutors led by a Democrat who refused to resign after being convicted of drunken driving.
Rubio: Rift with tea party constituency on immigration, "a real trial for me." Deflection: Go aggressive on a matter of common ground, which he did in pledging to take apart the health law. And stop talking about immigration. Response to Obama's 2013 State of the Union speech was remembered only for his clumsy reach for water. Deflection: Made fun of himself.
