Mitt Romney’s been having a good week at least when it comes to the polls. The Republican challenger is up three points over President Obama in a Reuters/Ipsos tracking poll released on Thursday. Romney, who is now leading the president 47 percent to 44 percent among likely voters, appears to be riding a post debate bounce, erasing much of Obama’s lead in the last week. On Wednesday, Reuters’ polling data showed that Romney was up 45 to 44 percent. However, the president is maintaining a narrow lead in several of the key swing states.
