ABC News’ Ron Claiborne Reports: The primary election in his own home state shows just how deep Sen. John McCain’s problems are with conservative voters.
In early returns, McCain was getting just under 50 percent of the vote. With 56 percent of the GOP ballots counted, McCain led former Massachusetts governor Mitt Romney 48-33 percent.
In his last re-election bid, in 2004, McCain got 77 percent of the vote.
ABC News analysis found that about two-thirds of Arizona Republican voters were conservatives and Romney beat McCain among that voter demographic 47-36 percent.
It’s also possible the immigration issue could be to blame. Anti-immigrant sentiment is strong among many white Arizonans.
Still, as a winner-take-all state, McCain garnered all 53 of the state’s delegates.
