Sens. Susan Collins of Maine and Lisa Murkowski of Alaska held their reputations as leading GOP moderates in 2013.  

In CQ Roll Call’s annual look at voting records , the two Republican women led the field of those most likely to vote with President Barack Obama on votes on which the administration clearly took a position, either through a formal Statement of Administration Policy or other expression of policy view.  

Collins backed the Obama view on such votes 75.9 percent of the time, with Murkowski following at 72.3 percent. They were the only Republican senators above 70 percent. That’s in line with the argument that Murkowski’s voting record might prove beneficial to the 2014 re-election case of her Democratic counterpart Mark Begich.  

Collins’ votes could serve her well in her own re-election bid as a New England Republican this year.  

Some of the votes were procedural in nature, meaning that the senators may argue they would have ultimately opposed the underlying legislation or nomination.  

The rest of the top five Republicans backing Obama’s views on significant votes are Arizona Sens. John McCain and Jeff Flake, as well as Rob Portman of Ohio. All of those senators supported Obama on more than half of such votes in 2013.  

McCain was recently censured by the Arizona Republican party for a so-called “liberal” voting record.  

Senate Democrats overwhelmingly backed their party’s president in 2013, the votes studies showed , to such an extent that procedural maneuvering by Majority Leader Harry Reid led the Nevada Democrat to technically “oppose” Obama more than almost all of his Democratic colleagues.
