The anger Democrats have embraced against the Brett Kavanaugh's nomination has turned criminal. Democrats in Maine have started a crowd sourcing fund to raise money for a challenger to Susan Collins if she votes for Kavanaugh. The if is important because they are threatening action based on a voting condition. That may very well run afoul of federal law.
If someone wants to run against Collins because of her vote, that is perfectly legal. But to tell Collins a punitive act against her will happen if she votes a particular way is illegal. Telling her someone will be given money to defeat her if she votes a certain way falls into that ethically.
At least one ethics expert consulted by The Washington Post said that it may very well violate federal bribery statutes, which prohibit giving or offering anything of value to government officials in exchange for any acts or votes. And Collins issued a sharply worded response through a spokeswoman that called it an attempt at extortion. “And anybody who thinks these tactics would work on Senator Collins obviously doesn’t know her,” spokeswoman Annie Clark said in a statement. “Senator Collins will make up her mind based on the merits of the nomination. Threats or other attempts to bully her will not play a factor in her decision making whatsoever.”
Another legal expert told Collins it sounds more like extortion, which I agree with. Senator Orrin Hatch is calling on Senate Democrats to publicly reject this extortion.
