President Trump is under siege. You've already figured that out. Whether it's from the news media, congressional Democrats, congressional Republicans (!) or disloyal members of his own administration leaking to the press, it's clear the Beltway establishment is determined to take him down.
He is trying to solve the very real problems this country faces. They don't want to let him do that. All these firestorms are endangering a very strong agenda that the country needs to see implemented, forcing the White House to deal on a daily basis with the latest bombshell, and to try to figure out who is right under their noses leaking like a faucet to the hostile press while hiding behind their anonymity.
That's bad, but I think the worst part might be this: When you're under siege like this, you can start wondering if anyone really has your back. To read the news every day, you'd think no one supports the president. His approval ratings are not good, but that's more a reflection of the overall chaos going on than a reflection of the actual governing he's trying to do. Most people don't even know what that consists of. What they're disapproving of is the general sense that everything is nuts in Washington.
