I predict that this will provide extreme motivation to the Trump supporters who elected him on 2016, and it will result in another 4 years of Trump as president.
People keep saying things like this, but I am coming to doubt it. While rabid, the "Trump base" is pretty small. Enough to swing a few percentage points at most. The rest of "the base" are more normal, Republican's or anti-tax, or wanting more restrained government, or religious, or wanting controlled spending etc. And Trump is not really any of those. If there is solid grounds for impeachment then I think that "other base" will be weaker, be more likely to stay home.
No matter what, the real thing that will decide the election will be who his opponent is.
No one actually knows though until the election results come in.
Prior history has shown us that even with solid grounds of impeaching someone, they still can be re-elected easily. I would put Perjury and Obstruction of justice in the same class of crime. I think you'll be surprised to find that many Republican's view the actions laid out in the Mueller report to not constitute obstruction. Telling McGahn, for instance, to find ways to remove Mueller due to conflicts of interests, does not, in my view, constitute an obstruction of justice (He never said end the investigation). Removing Comey from his position as Director of the FBI does not constitute obstruction of justice, the Director serves at the pleasure of the President. And besides that, he had a recommendation from the very person who opened the investigation recommending his firing.
I know many, many Republicans (myself included) who held their nose while voting for Trump. Now they are far more enthusiastic about supporting him. And the polling numbers with Republicans reflect that.
My non-scientific poll of a very small sample size of Trump voters that I know tells me that many agree with your assessment. But, in addition to your assessment, they don’t view the Mueller report and follow on democratic reaction as separate from the last 2.5 years of continuous spewing of bile and hate from those on the left. All remember
- the death threats towards the electors before the inauguration,
- the riots the day of the inauguration,
- mad Maxine Waters calls for impeachment on day 1,
- the pussy hat March,
- Kathy Griffin’s celebrated photo with a fake Trump head,
- The crooked Avanattis hundreds of appearances on MSNBC bashing Trump,
- the false accusations of drugging and gang rape on Justice Kavanaugh,
- the race baiting by Democrats in Congress
- Adam Schiffs continued false accusations of Trump with no evidence.
- and all of the continued antics by the left to this day.
All are sick and tired of the BS from the left and there is nothing short of proven and real criminal behavior by Trump that will get the vast majority of Trump voters to listen to a single word that is said or typed by any left leaning, Trump hating liberal. Period.
