AIKEN, S.C. (AP) - Sen. Lindsey Graham is showing no signs of changing how he operates as he faces the biggest challenge of his political career.
Willing to buck the public tide in South Carolina, Graham has backed military action against Syria, an immigration overhaul that sets a path to citizenship for some in the U.S. illegally and President Barack Obama's Supreme Court nominees.
His three Republican challengers are coming at him from the right, arguing that he's not conservative enough. They're also noting that the 58-year-old lawyer has been in some political office since 1993 and shows no sign of stepping down soon unless he gets voted out.
To win, they face their own hurdles. Graham remains popular with less die-hard Republicans and has $6.3 million in his campaign bank account.
