Class warfare fail.

( — President Barack Obama’s approval has hit an all-time low among the poorest Americans, according to the Gallup poll. Meanwhile, when compared to the other income brackets reported by Gallup, Obama’s approval is highest among the richest Americans.

In the week of June 20–26 — the most recent week published by Gallup — only 45 percent of Americans in the lowest income bracket reported by the polling company (those earning less than $2,000 per month) said they approved of the job Obama was doing as president.

Gallup publishes the president’s weekly approval numbers among Americans in four income brackets: those earning less than $2,000 per month, those earning between $2,000 and $4,999 per month, those earning between $5,000 and $7,499 and those earning more than $7,500.

In Gallup’s most recent survey, Obama had majority approval in none of these income brackets.

However, of the four, his approval was highest — 47 percent — in the richest bracket, those earning more than $7,500 per month.

His approval rating last was 42 percent among those earning $2,000 to $4,999 per month and 43 percent among those earning $5,000 to $7,499 per month.
