More potential challengers to Florida Rep. Alan Grayson, D-Fla., are deciding to take a pass on running against the freshman Democrat.

Former state Sen. Dan Webster, who was seen by many Republicans as someone who could clear the GOP field and help the party avoid a contested primary, took his name out of consideration Tuesday afternoon.

“This has been a very difficult decision for me personally, especially because of the tremendous outpouring of support that has flooded me from all sides,” Webster said in a statement to the Florida press. “However, in spite of this incredible encouragement, I still have a certain check in my spirit, prompting me to follow a principle that has always served me well: ‘When in doubt, don’t.'”
