Washington (CNN) - GOP Sen. Jim Bunning is standing alone - much like a baseball pitcher on the mound - as he continues to block a measure that would extend cash and health insurance benefits for the unemployed.
The Kentucky Republican, who is retiring at the end of this term, argues that he doesn't oppose extending the programs; he just doesn't want to add to the deficit.
CNN Senior Political Analyst Gloria Borger, who spoke with a Republican in the Senate, said members of the GOP feel Bunning "has the right idea" in questioning how the extension would be paid for, but think "it is the wrong fight for them to wage right now."
The fear from many Republicans, Borger noted, is that it plays right into the Democrats' narrative that Republicans are obstructionists.
Bunning's views, Maine GOP Sen. Susan Collins said, "do not represent the majority of the Republican caucus." Senate Majority Leader Harry Reid called Bunning's legislative tactics "terribly inappropriate" and "very out of line."
The tensions have seemingly taken a toll on Bunning, who is the first member of the Baseball Hall of Fame to serve in Congress.
Bunning, observers have noted, has a history of being abrasive.
