How did president Johnson win the support of the american people during his first year in office?how did americans show their support

Lyndon B. Johnson was considered one of the most brillant
politicians of his time, and, as stated above, he rode on the romanticized "Camelot" of
the Kennedy presidency.  Known for his "Johnson treatment," the figurative
arm-twisting of powerful politicians in order to get legislation passed,  Johnson,
indeed, rode into the presidency on the wave of Kennedy's ideals.  His "Great Society"
included laws that upheld civil rights, furthering what Kennedy had begun.  He
instituted hiring quotas for minorities; he pushed through legislation on Medicare and
Medicaid with the Social Security Act of 1965; and he began a "War on
Poverty."

But, Johnson also greatly escalated the war in
Vietnam, a war that became increasing unpopular. (Rumour has it that he profited from
the war with a bridge company in his wife's name.)  Consequently, the president who was
so popular in 1964 and 1965 grew increasingly unpopular; in fact, he was despised by
many at the end of his term.  He withdrew from the campaign for re-election with the
growing opposition to the Vietnam War after he had a poor showing in New Hampshire in
1968.  After the debacle of Vietnam, Johnson is considered a failure in foreign policy,
but he is ranked favorably with some historians for his domestic
policies.
