President Trump is a politician who campaigns for other intensely.
This has got to have gotten incumbents attention. He is going to try to remake the Senate.
The rallies are interesting because if you've followed him from the beginning most of it is old hat however he does add lots of little details if you listen.
For example his side comments about Little Kim perhaps being pretty smart or a lunatic. That tacit admission that Kim is playing his cards well at this point is interesting. His drop dead honest explanation on why he is supporting Luther Strange. There was something else but I forgot now.
These rallies are key - they are good for him
You’d think it would have been obvious during the campaign by the size of crowds he drew that Trump had tapped into lightning. The dems seemed oblivious as Hillary eschewed personal appearances entirely. Dumb dumb dumb.
