Huh?
Ever bought clothes for a two year old? Those little guys grow like weeds. :)
Yeah, what anymouse said... I think the 2 year old observation is a hopeful view of the future, in which the new voters of the election of 2020 are going to be predominantly Republican. We're in one of those periods where the previously dominant party has bled itself, as when the Whigs fell apart, and later the Dims split (election of 1860), and still later the Pubbies (election of 1912; although there were four candidates that year, so both votes were diluted; TR I believe actually beat Taft, but Wilson had the greatest plurality; just to be on the safe side, Wilson arrested and jailed his Socialist opponent, Eugene V. Debs) who recovered in 1920.
Unfortunately, the party offered three different presidential candidates in the four elections from 1920 to 1932, which showed internal turmoil, and embraced the crazed and glazed fanatics (women who demanded Prohibition and Emancipation; isolationism and economic protectionism). Such an embrace is mirrored by the Dims since 1968 -- abortion on demand, trampling the flag, slandering veterans, calling for unilateral disarmament and surrendering national sovereignty...
In the 1964 election, LBJ picked a liberal running mate in order to line up the votes to reject the renegade delegation from Mississippi (a delegation which happened to be black), waved the bloody shirt (JFK's assassination), won by a landslide, and pulled in a huge majority in both houses of Congress. He enacted civil rights legislation, called for a so-called Great Society, pushed the space program, and simultaneously engineered the Tonkin Gulf Resolution. Vietnam ate the US budget and made the peacetime deficit balloon -- and ultimately cost LBJ a second full term.
Nixon won in 1968 by a slim margin, only slightly fatter than JFK's slim margin in 1960. Nixon had attended the raucous 1964 "Goldwater" convention, but his tranformation from a washed-up ex-politician to the President of the United States was remarkable (still is). LBJ's presidency was broadly ambitious, but turned out to be a miserable failure and (other than civil rights and the Moon landings) a dark legacy the US still struggles to overcome.
Nixon's narrow victory and lack of support in the Congress makes his performance as chief executive all the more amazing. He managed to extricate the US from Vietnam -- a debacle, a fiasco, handed over fully formed -- after cancelling college deferments and bombing North Vietnam into negotiations. He opened China and with Mao issued the Shanghai Communique. During the darkest days of Watergate, he sent "everything that will fly" to support Israel in the October 1973 war and the US outlifted the USSR, which had a very much shorter (and less hostile) distance to fly. The diplomatic activity surrounding the Yom Kippur War helped Sec of State Kissinger pry Egypt loose from Soviet influence, led to the Egypt-Israel peace treaty, and reduced Soviet influence in the region.
In 1972 the "anti-war" (pro-war, pro-single party state, pro-Soviet) Left had taken over the Democratic Party -- at the convention that year even my consistently Dem parents were appalled by the "Democrats Abroad" delegation. Nixon won 49 out of the 50 states, losing only Massachusetts and the DC. But for cooler heads among his inner circle, he might never have self-destructed with the break-ins (Ellsberg, Watergate). Without the impeachment, it is unlikely that Nixon's successor would have taken office before 1977.
