If there is an investigation bringing down trump, i REALLY hope it'll take pence with him.
Honestly, I don't think chances at impeachment are good at the moment. Sure, the FBI has been investigating the guy and there is a special prosecutor that both sides like but... Even if they do find something, for the time being an impeachment is at best unlikely. As far as we know, the following are the things that are being investigated:
-Whether trump's campaign colluded with Russia for the email thing
-Links between russia and the trump campaign.
And I would guess they are looking into whether trump's colleagues and trump himself have taken any money from russia.
The first thing is that none of these are things trump specifically would have had to be involved with. They could find half his campaign was involved in all possible charges and even then trump himself could walk home free. For another, those guys would probably take the fall before trump himself does. As for the collusion with russia regarding the emails... Honestly, this is absolutely worth looking into given the circumstances but overall I don't see any reason for there to have been a collusion here. I mean, why? The most likely scenario is that the FBI is going to conclude that russia basically acted out based on what trump said (russia should hack hillary) but he wasn't actually a part of the process beyond that. In which case he walks home free. Even in the extraordinary case that they get evidence that trump's campaign was in a meeting with a russian agent of sorts and came to an agreement odds are they would take the fall before trump himself does. Now, it is perfectly plausible trump is actually stupid enough to do that and not even realize it's illegal but overall it is just unnecessary. Russia's goal is invariably to cause political instability. They don't need extra motivation to do this. If anything, this is a win-win situation for russia, they never had anything to lose. Even now you have putin offering transcripts of the meeting trump had with the russian guy recently. Trump is probably enough of a moron to think putin had trump's best interest at heart but we all know that was not meant to help trump but rather to create more political chaos.
Now, even if something is proven then the issue is the impeachment process itself. Republicans control the house and the senate. And impeachments are an issue on which parties invariably vote along party lines. A number of presidents have not been impeached basically because of that. With that in mind, it would take extraordinary evidence and extraordinary charges to actually impeach trump for the time being. It would have to be something grotesque enough to even get the majority of the republican party to want him out. Which arguable would require no less than trump himself literally taking money from russia through some deal or another. Which granted, trump is actually stupid enough to have tried to pull off. For an impeachment to be reasonably possible it would have to happen 2 years from now and only if democrats regain control.
Now, I will play devil's advocate here and suggest why an impeachment is probably a bad idea anyways: DEMOCRATS.
Democrats saw the results of the 2016 election and decided to quadrupled down on the idiocy that lead to their defeat. They did not learn their lesson. Overall polling still shows democrats are less popular than republicans. Hillary clinton started her own super pac and whatnot and plans to remain relevant even though she is at least as unpopular as she was last year. She might even be planning on running for president. In a reasonable world she would get precisely zero democrat support next election. Bernie remains literally the most popular politician in the US and democrats rather than embrace the guy treat him like an outcast, a lunatic and a moron. Democrats have their own heads so far up each others asses they basically live in a separate reality. Democrats make the point, correctly mind you, that republicans live in an alternate fact free reality. But they don't realize they also live in an alternate reality where people don't hate their guts. With the democrat party as it is now, 8 years of trump is an actual possibility.
Now, with that taken in consideration, what happens when trump gets impeached if democrats are a party that is currently hated this much? As democrats stand they are not a popular party at all even in spite of trump. They stick by hillary clinton, plausibly the most hated politician in the US. Maybe trump is disliked more than she is. So... can you imagine the next elections if a republican like pence or ryan takes over? Hillary wouldn't necessarily beat trump if she ran again and a generic democrat would have trouble beating a generic republican specially if the years of the current term are dedicated to damage control over the idiocy that would have been the trump administration. And sure, trump's agenda is awful. But dismantling the EPA, tax cuts for the very wealthy, repealing obamacare and all the other stuff trump is doing is not actually trump idiocy. That is generic republican idiocy.
