Harford County Executive David R. Craig (R) is set to become the first candidate for Maryland governor to take to the airwaves this year with the debut of a radio ad on Friday, his campaign said.

Craig’s 30-second spot touts his plan to reduce and eventually eliminate the state’s personal income tax, with the Republican hopeful telling listeners, “It’s time to vote yourself a raise.”

Craig’s campaign said the ad will air during select programs on two Baltimore-area talk radio stations through March.

Craig, who launched his campaign in June, is seeking to distinguish himself in a crowded GOP field in which none of the contenders reported having much cash on hand in January.

In a Washington Post poll published last week, Larry Hogan, a Cabinet member under former governor Robert L. Ehrlich Jr. (R) who entered the race late last month, had the support of 17 percent of Republican and GOP-leaning independent voters.

He was followed by Craig with 13 percent, Charles County businessman Charles Lollar with 10 percent and Del. Ronald A. George of Anne Arundel County with 4 percent.

At a business summit he organized in Annapolis on Thursday, Hogan told a breakfast crowd of more than 300 people that would change the state’s tax code to make it more competitive with other states.

“We don’t necessarily have to have the lowest taxes in the country, but we certainly can’t afford to have the highest,” Hogan said. “Our goal should be to ensure that excessive taxes are not the reason major companies choose to do business elsewhere.”

Hogan also said that if elected governor, he would veto any bill that makes it more difficult for families and businesses to stay in Maryland.

Lollar, meanwhile, was scheduled to start an “Economic Recovery Tour” on Thursday night in Westminster. It is one of 15 stops advertised by his campaign. Lollar has also proposed scrapping the state’s personal income tax.
