I'm not sure Trump has time. There is an election coming in less than 2 years. If the economy is perceived as bad then a lot of people will vote with their wallet.
The Left wing media is going to try and paint a grim picture, deserved or undeserved.
Historically, the opposing party makes gains during the mid terms. If the Demorats take either the house or the senate, the legislation slows to a crawl and/or stalls.
China thinks long term. The 5 year plan. The USA is quarter to quarter. Trump needs to score some wins on the Tariffs quickly. from a Chinese perspective, if they can wait a few years, Trumps gone and perhaps they get someone who's friendlier towards them. America blows with the political winds. Wait awhile, and the wind will shift.
It's hay season. Trump and the republicans need to make hay and get it in the barn before the season changes. That's a problem for them. They can't seem to get everyone on board. The few radical republicans will block legislation because it doesn't have every thing they want in it. This has been a big "lose" for them. The Democrats fight like hell with each other and then vote as a block. The Republicans could learn something from them in this regard.
The republicans have the house, senate and whitehouse. Last time, other than the tax bill, they didn't make hay much less get it in the barn. The republicans have a huge leadership problem that they can't seem to work out. I they can find someone the step up and actually lead then they have the opportunity to make some great changes. If they continue along the same lines as they have in the past, we'll get little to nothing.
