Stay classy, Mr. President

All presidents use their influential position as a bully pulpit for advocacy of issues important to them.  But, has any other president in living memory used their office as a platform for mocking and caricaturing his political opponents?

Arizona Daily Star, May 11:

Touting gains on border security and mocking Republicans' insatiable appetite for border enforcement, President Obama said Tuesday it's time for immigration reform.

The administration has gone "above and beyond" what Republicans asked for on border security when the last round of serious immigration reform debate stalled in 2007, Obama said in El Paso on his first trip to the U.S.-Mexico border since becoming president.

"All the stuff they've asked for, we've done," Obama said. "But, I suspect there's going to be those who try to move the goal posts on us one more time."

They'll now call for even more Border Patrol agents and a higher fence, he said.

"Maybe they'll say we need a moat? Maybe they'll want alligators in the moat?" Obama said. "They'll never be satisfied. And I understand that; that's politics. But the truth is that the measures we've put in place are getting results."

Way to promote reasoned debate, Mr. President.

Mock all you want, but can you prove that the border is less porous now than it was when you entered office?  I’d love to have some south Texas ranchers in the room with you when you answer.

P.S. A moat with alligators might actually work.
