If political campaigns have nine lives, nervous Republicans feel Mitt Romney has used up at least eight.

While insisting the party is still short of full-fledged panic, the video of Romney disparaging Americans who don’t pay income taxes and the GOP nominee’s consistently unsteady explanation of what he meant has prompted a chorus of fed-up Republicans to speak out about a campaign they see as badly in need of a jolt.

Elected officials, donors and operatives are irritated about facing yet another distraction, but the surreptitiously recorded clips have triggered a round of broader complaints over Romney’s fundraising-focused schedule, lackluster candidate skills and a seemingly adrift campaign that trails in key battleground states with less than 50 days to go.
