Story highlights Some are voting for Hillary Clinton, others say no way

Part of the effort is organized by Clinton and part are just fed up with Trump

(CNN) Another day, another bunch of Republicans fleeing Donald Trump.

In what seems like a nearly daily occurrence, Republicans are bolting their party's nominee. But if not him, who? Some are going so far as to endorse Democratic rival Hillary Clinton; others, like Maine Sen. Susan Collins on Tuesday, are just saying they can't stomach supporting the GOP nominee.

Regardless, the large number of Republican defections would seem to help Clinton.

In some cases, the defections are clearly organized -- and even announced -- by the Clinton campaign. Other Republican defectors say they are acting independently of the campaign.

Last week, Rep. Adam Kinzinger of Illinois announced he will not back Trump, telling CNN's Wolf Blitzer: "I'm an American before I'm a Republican."
