Republican Sen. Saxby Chambliss has lined up his first big runoff campaign headliner: Republican presidential candidate John McCain.    Chambliss spokeswoman Michelle Grasso said the date still is being worked out but McCain will be here sometime before the Dec. 2 runoff.

Republican John McCain claimed Georgia’s 15 electoral votes, beating back Democrat Barack Obama’s drive to turn the GOP stronghold blue. The win in Georgia was bittersweet. McCain already has conceded defeat to Obama, who’s now White House bound. But GOP Senator Saxby Chambliss wasn’t strong enough to avoid a runoff election.  He finished with less than 50% of the vote.
