Wouldn't it have been easier, cheaper and more efficient to assassinate her husband and make her his replacement as President or VP on the Democratic ticket, instead of assassinating her husband on election night, framing his VP, paying off the Electoral College to elect the Republican candidate, blackmailing the Republican VP-Elect, hoping they'd choose her (the wife of the Dem. President-Elect) to replace the Rep. VP-Elect, killing the new (Republican) President-Elect at the inauguration, swoop in as the new Republican President, and hope nobody notices that she was standing on stage next to both Frankie and Mellie when they were assassinated, or find it weird that the widow of an assassinated Dem. President-Elect would become the Rep. President a few months later?
