Yeah, you’re right.
I want him to start smash mouthing Hillary now.
A little premature to focus on Hillary. If Biden jumps in (looking more likely now) Hillary will not necessarily win nomination. Besides voters are notorious for short memories.
Right now task#1 for Trump is to win GOP nomination. There will be almost 3 months afterwards to focus on democrat nominee, whoever it is. 3 months is stretching voter’s attention span already!
A successful businessman is successful because he/she learns to prioritize what needs done first. Whether Trump is operating correctly or not is best judged by looking at all polls done each week.
