Take on the Gallup poll

A Gallup poll yesterday showed Trump hitting 49% which is his highest approval rate since taking office and for the life of me I can't understand why.
Trump's been impeached, there is talk of censure and his handling of most situation have been an abject failure
But this is where we are now, a president whose only interest is his own promotion, one who doesn't see the presidency as having any greater value than what he thinks he can make from it...and somehow Americans are buying in.
There is no part of me which will understand the appeal to this man after having seen him as our commander in chief for the last 3+ years. Yet half my brethren now approve of him. I'm flabbergasted
