(Las Vegas) — Rudy Giuliani took shots at President Barack Obama today as he visited Republican supporters while stumping for Mitt Romney.

The fomer New York City mayor questioned Obama’s business, ethics and abilities to run the country in a 20-minute speech in Las Vegas.

“He killed your jobs in Las Vegas. Directly! Killed ‘EM! With his stupid comment on boondoggles. That cost you billions and billions of dollars, and thousands and thousand of jobs”, Giuliani said.

In the speech, Giuliani chuckled about the possible voting habits of Las Vegas residents. “Anybody in Las Vegas who is going to vote for is out of their mind.”

Giuliani said that if Obama is re-elected in November, he will abuse his power and promote  socialism that will boost taxes for Americans.
