Marco Rubio has nearly doubled his support in New Hampshire since the beginning of the summer, according to a new Suffolk University poll that shows the Florida senator riding strong debate performances.
Some 11% of New Hampshire residents who intend to vote in the Republican primary in February say they support Rubio, up from 6.8% in the same poll released June 23. Rubio is now in second place behind Donald Trump in the state.
Rubio gained wider national attention after the Republican debates, though conservatives have begun to call his commitment on immigration and foreign policy into question. Rubio helped formulate the failed bipartisan immigration reform bill in the Senate in 2013, which gave undocumented immigrants a path to citizenship.
He released his first television advertisement on Sunday, focusing on national security issues.
