Obviously any case against Trump would have to be pretty much rock solid. I just don't see any prosecutor going after charges for purely partisan purposes. However the age old adage "no one is above the law" is something that almost all US citizens-- except many Trump supporters-- believe strongly. Trump and many of his associates are dirty.
The Southern District of NY (SDNY) is digging into decades of corruption that might otherwise not have gotten as much attention were he not president. Thes hush money payments to prostitutes is the least of his legal problems. Don't forget that phony University scam, monies stolen from his inauguration, flagrant lies on tax returns, money laundering schemes with overseas banks, illegal contributions with a Pro-Trump super PAC, the Trump Foundation (AG statement that it involved a “shocking pattern of illegality"), numerous emoluments offenses, and on, and on, and on. By far the most corrupt administration in recent US history.
Going to be kinda' hard for him to bluster his way out of all that.
My personal opinion, an opinion shared by many others, is that he did not ever want to be President in the first place. Now that he's in, he'd prefer to not get reelected (too hard a job) but rather lose and play the victim card. Believing in hs delusional mind that he really won save for all the voter fraud.
HOWEVER, if he's out, there's the SDNY waiting for him! Mr. Rock? Meet Mr Hard Place.
