CNN projects that former Gov. Robert Ehrlich will win the state's Republican gubernatorial primary. The victory would mean that Ehrlich will now face off in November's general election against Democratic Gov. Martin O'Malley, who defeated Ehrlich in his 2006 bid for re-election for a second term.
In Tuesday's primary, Ehrlich faced off against businessman Brian Murphy, who was backed last month by former Alaska Gov. Sarah Palin.
"I'm honored to endorse Brian Murphy for Governor of Maryland. Brian is a pro-life, pro-Second Amendment commonsense conservative and a firm believer in the free market and the cause for energy independence," said Palin in early August, in a statement posted on her Facebook page.
Palin recorded a robocall in support of Murphy in the final day before the primary.
The Republican Governors Association is already congratulating Ehrlich.
"Maryland voters know the difference Bob Ehrlich can make for their state," said RGA spokesman Chris Schrimpf in a statement. "Bob fought off Democratic tax increases and helped create 100,000 private sector jobs. Under O'Malley all those jobs and more were lost and what's worse taxes went up by 1.3 billion dollars, the most in history. The question every Marylander will ask themselves is, are they better off now than they were four years ago?"
The Democratic Governors Association followed minutes later with a statement as well.
"Bob Ehrlich is really good at saying one thing and doing another," said DGA executive director Nathan Daschle in a statement. "He campaigns on lowering taxes, but as governor he raised taxes and fees by $3 billion. The biggest spender in Maryland history now argues he'll be a fiscal hawk. And though Ehrlich says he's on the side of the people, he's spent the last few years making a lot of money working for special interests. He couldn't be more out of step with the mainstream of Maryland. The bottom line: an Ehrlich sequel would mean moving the state backward."
