A political aide to former Maryland Gov. Robert Ehrlich was convicted Tuesday of conspiring to use election-day robocalls in an effort to suppress black voter turnout during the 2010 gubernatorial election.

Paul Schurick was found guilty of all four counts he faced, including conspiracy to influence or attempt to influence a voter's decision whether to go to the polls through the use of fraud and conspiracy to publish campaign material without an authority line. A stoic Schurick comforted his wife in the courtroom after the Baltimore jury's verdict was read, but declined to comment.

His attorney, A. Dwight Pettit, said they will appeal.

Prosecutors argued the calls that went out on the evening of Election Day to about 110,000 voters in Baltimore city and Prince George's County — two jurisdictions with high percentages of black voters — were an effort by the Republican campaign to reduce the number of black Democrats voting in heavily Democratic Maryland.
