Russia/Trump. Russia is particularly slimy among the world's great powers. And it pokes its head around most of the world. Has for 70 years. If you were youngish during the Cold War - and likely a Republican-minded person - did you view Russia as a fine, acceptable nation? My bet is not. How doth your opinion change? Capitalism? Is that what brought you over on to their side of the court? Very crooked country. Don't trust them.
Mole Hills? So, why doth the President crash so-spectacularly? Is it simply because of a media conspiracy? Well, the media are by now unquestionably out to get him for the most part. But, they have been given so many paths to follow by leaders and "leakers" within government. Do you actually think "all Republicans' are with Trump now? Nope. He won't be the party's next candidate in 2020 because they are realizing that he will be their ticket "into the ground." Next Congressional elections are in just 16 months. Many will change their minds by then.
