Every 52 years, the Republican Party implodes.
The GOP was formed in 1854 and elected Abraham Lincoln in 1860.
52 years later, on 1912, the GOP had a civil war and Teddy Roosevelt split off from the Republicans supporting William Howard Taft, into the Progressive (Bull Moose) party, allowing Democrat Woodrow Wilson to become president.
52 years later, in 1964, the Republicans nominated Barry Goldwater, splintering the party. Many Republicans refused to endorse him; some even backed Lyndon Johnson. The election was a rout, with the worst defeat in modern history.
And now, again 52 years later, it looks like the Republican party is about to implode for the third time. If it does, not only is the presidency in jeopardy, they will probably lose the Senate and maybe even the House.
