State Attorney General Tom Corbett earns nearly 50% support again this month in Pennsylvania’s race for governor, while only one of his Democratic opponents seems to be gaining any traction.

The latest Rasmussen Reports telephone survey of likely voters in the Keystone State finds Corbett with 45% to 49% of the vote depending on his opponent, but this marks no change from last month. In February, his best showing to date, the Republican picked up over 50% support in two of the three match-ups.
