Hilary Clinton may not be a "monster," but according to vice presidential hopeful Mitt Romney, she and Barack Obama are "chihuahuas."

Sen. John McCain has not picked his running mate yet, but Romney is campaigning for the presumptive GOP candidate as if he had the job. According to the transcript of an interview airing tonight on FOX News Channel’s Hannity and Colmes, he's practically slobbering over the No. 2 job:

“I think any Republican leader in this country would be honored to be asked to serve as the vice presidential nominee, myself included. Of course this is a nation which needs strong leadership. And if the nominee of our party asked you to serve with him, anybody would be honored to receive that call…and to accept it, of course.”

Despite the serious support from the Bush wing of the GOP, McCain still has a small problem with Mitt — he has utter contempt for the former Massachusetts governor. Maybe that's why Romney is trying to show he'll be a pit bull on the campaign trail.

"Listening to Hillary Clinton and Barack Obama talk about experience in a national security crisis is like listening to two chihuahuas argue about which is the biggest dog. When it comes to national security, John McCain is the big dog, and they are the chihuahuas."

McCain will drop by Utah March 27 to visit his early supporter and pal (and less-likely veep possibility) Gov. Jon Huntsman and to wring money out of state Republicans.

The Christian Broadcasting Network (apparently OK with a Mormon as vice president) likes the idea of McCain-Romney match.

Romney is loved by the big talk radio hosts and could be someone the base goes for. Plus, the VP needs to be the attack dog and Romney has shown is up for that challenge.
