With gun control calls growing louder, it appears that Sen. John McCain (R-Ariz.) has emerged as a key player if Senate Democrats are to have any chance of passing legislation to expand background checks for private sales of firearms.
TheHill.com reports that McCain and Sens. Susan Collins (R-Maine) and Dean Heller (R-Nev.) are at the top of a list of Republicans considered most likely to sign on to legislation expanding background checks after talks with Sen. Tom Coburn (R-Okla.) stalled earlier this month.
Expanding background checks is hotly contested by both proponents and adversaries who site research in both directions.
