The Republicans have to find a decent candidate before the general election. I don’t think the GOP will survive one more election with Trump.
You are mistaken on both counts. There is no one -- other than Vivek -- who can be seriously considered a candidate, let alone a "decent" candidate. And Vivek does not have the track record of Trump (when you ignore all the nonsense arising from Trump Derangement Syndrome, and all the lies about Trump).
And the GOP is simply a bunch of RINOs (traitors and cowards for the most part) who never stood with Trump to begin with.
His primary mistake was to run as a Republican, rather than establish a true conservative party. The real Republicans would have then abandoned the GOP in droves. Just look at the huge crowds at Trump's rallies all along. But the MSM will never show this to the public.
If Trump was not a serious threat to the Democrats, Barack and Michelle Obama would not be running scared right now. And Biden would not be calling him Hitler (hoping that his lies will sway people). Neither would the Biden administration (and the Democratic governors) be doing everything unlawful to stop him. They have made the DOJ and FBI lawless thugs in order to stop Trump (as well as conservatives and Christians). They have flooded the country with millions of illegal invaders to ensure fraudulent voting wins the day.
So now it is for the Lord to shut down these evildoers who wish to utterly destroy America and its freedoms, since there are many Christians who have also been destroyed.
