This is not LBJ’s era. Lyndon Johnson had an approval rating of about 70 percent when he routed Goldwater. That’s 25 percentage points above Obama’s! Johnson had the legacy of JFK at his back. More than a third of the nation identified as liberal then. Only a fifth does today.
Goldwater also ran in a time before the two parties were hyper-polarized. Almost half of all Republicans approved of Johnson around Election Day 1964. By comparison, only about one in 10 Democrats approved of Bush on Election Day 2004. The same share of Republicans currently approve of Obama, according to Gallup.

The economy grew 1.7 percent in Obama’s third year.
