According to Craig Hamilton-Parker, a Psychic who predicted Trump’s election win and Brexit a Trump impeachment effort in mid-2018 will fail and make him more popular.
His prediction was:
An attempt to impeach Donald Trump in mid 2018 will fail and he will become more popular as a result.
He didn’t mention who won the 2018 elections but it doesn’t seem to matter. If the Democrats go all in on impeaching Trump and fail they will risk becoming more unpopular than they already are.
