Next years election cycle has already been discounted by the market. The market is already expecting solid GDP growth, solid earnings, etc.
IMO, people aren't screaming about a top. If you turn on CNBC, everyone is a perma bull. Larry "pro growth" Kudlow is literally dancing in the streets. The "New bull market" knuckleheads are out in full force. Bad news is swept under the rug (i.e. FRE debacle). Good news is treated like royalty.
