The field for the 1st Congressional District seat vacancy created by Tim Scott’s propmotion to the U.S. Senate is growing by the hour today.

Former S.C. state senator John Kuhn formally announced his bid this afternoon. Kuhn represented parts of Charleston and Berkeley counties in the S.C. Senate from 2001-2004.

Kuhn, 50, is an attorney living in downtown Charleston.

Democrat state Rep. Wendell Gilliard, who represents parts of downtown Charleston, also announced today he is exploring a bid for the seat.

“The primary question for Rep. Gilliard is this: ‘Can a Democrat with the full support of their state and national party win the 1st Congressional District seat?’ ” he said in a statement today.

Scott was picked by Gov. Nikki Haley on Monday to fill the vacancy created by Republican Jim DeMint’s resignation.

The field could reach 10 or more, by some counts, of those interested in the open seat.
