"Our best isn't good enough — right now our eyes are far-reaching," Anderson, who first landed the cover of the mag in 1989. "Please let's show the good in us ... The brilliance ... The wonderful ... It's abundant — it's just not tapped as it should be."

The mother of two, who refers to herself as "just a sex symbol" even calls out "All the negative ads run by our politicians," and urges them to "Put that money to good use."

She also shows her support for President Barack Obama, writing, "So many are with you ... I can think of many positive parts of now ... That you spearheaded."

Her final thought? "May all your bombs be bombshells."
