Florida Sen. Marco Rubio is well-positioned to do well as a potential Republican presidential contender if another candidate stumbles because GOP voters view him so favorably, according to a new poll.
The Democratic-leaning Public Policy Polling found that Rubio had the highest approval rating -- 55-22 percent -- of the nine politicians featured in its survey. In contrast, former Florida Gov. Jeb Bush's rating was 39-37 percent. But Rubio is not most voters' first choice, which is why the pollsters said he could benefit if a competitor has a setback.
Texas Sen. Ted Cruz, who became the first Republican to formally declare his candidacy last week, has seen a surge in popularity in the past month, according to the poll results. But the leading hopeful in the crowded Republican field remains Wisconsin Gov. Scott Walker, with 20 percent support, which is down from last month's 25 percent. Bush is in second place at 17 percent; Rubio's tied for sixth at 6 percent. The polls error margin is 4.7 percentage points.
