1933: Assassination attempt on FDR succeeds, Garner is President

Ouch. That would have sucked big time.

I think the fact that the Democrats controlled Congress would help in still getting the New Deal reforms passed, but not until at least 1934 or maybe even 1936 when they controlled a good number of seats in both houses could they override Garner's vetoes on any recovery legislation.

He would lose in the 1936 primary for sure though to someone much more liberal.
