I would recommend that the possibility of prosecution for sedition be explored in a question to the President at a news conference. e.g. "Mr. President, the media has, for years now, been filled with stories about prominent politicians and others badmouthing our war effort and giving aid and comfort to the enemy. This type of talk discourages our gallant troops and often takes place on foreign soil. Given our history of dealing with sedition during wartime do you have any plans to consider prosecutions for seditious acts?"
And here all this time I thought I was just trying to think for myself and encourage others to do the same.
