(WASHINGTON EXAMINER) Sen. Marco Rubio’s support among Republican voters has dropped 15 points since February, shortly after he took a high-profile role in advocating comprehensive immigration reform, according to a new Rasmussen poll.

The survey, of 1,000 likely voters conducted June 20-21, found that 58 percent of Republicans nationwide view Rubio favorably. That is down from Rubio’s 73 percent favorable rating among Republicans in mid-February. Rubio introduced the Gang of Eight immigration initiative in the last days of January.

The intensity of GOP support for Rubio has also waned. In February, 44 percent of Republicans said they had a very favorable opinion of him. In the new poll, that number is 21 percent.
