At least three Republican electors say they may not support their party's presidential ticket when the Electoral College meets in December to formally elect the new president. That prospect is escalating tensions within the GOP and adding a fresh layer of intrigue to the final weeks of the White House race.  (AP Photo/Charles Dharapak, File)
