Paul Ryan has propelled Mitt Romney into the lead over President Obama in the critical battleground state of Wisconsin, according to the latest survey from liberal-leaning Public Policy Polling.
Romney edges Obama 48 percent to 47, according to the poll, which has a 2.7 percent margin of error.
It’s the second consecutive survey of Wisconsin to find Romney has overtaken the president following the selection of Ryan as his running mate. A survey earlier this month from conservative-leaning polling outlet Rasmussen also gave Romney a 48-47 lead in the state.
According to PPP, Ryan has helped shore up the Republican base in Wisconsin. Romney has stretched his lead over Obama among Republicans from 78 percentage points to 88. The former Massachusetts governor has also seen gains among independents in the state, cutting Obama’s 14-point July advantage to only 4.
