Sen. Marco Rubio (R-Fla.) has emerged unscathed from a controversy stemming from the date on which his family emigrated from Cuba, according to a new poll Friday.

Forty-nine percent of Florida voters approved of Rubio’s job performance - unchanged from late September, reports a new Quinnipiac poll. Only 29 percent disapproved of his job performance, slightly down from 31 percent in September.

Rubio found himself embroiled in controversy in October when the Washington Post wrote a story disputing his claims that his parents had come to the United States following Castro’s takeover in Cuba. In fact, Rubio’s parents had obtained American residency over two years before Castro seized power in 1959, although Rubio’s mother visited Cuba shortly four times after the dictator’s takeover.

In response to the story, the Florida Republican wrote an editorial for POLITICO to defend himself.

“If The Washington Post wants to criticize me for getting a few dates wrong, I accept that. But to call into question the central and defining event of my parents’ young lives – the fact that a brutal communist dictator took control of their homeland and they were never able to return – is something I will not tolerate,” Rubio wrote.
