The Republican Party’s plan to ride back to power on the TeaBag Express seems to be running into a few roadblocks — the Tea Party candidates themselves.

In Kentucky, a volunteer for tea-party-backed Senate candidate Rand Paul was videotaped stepping on the head of a liberal protester. In Delaware and Colorado, Senate hopefuls Christine O’Donnell and Ken Buck, respectively, are under fire for denying that the First Amendment’s establishment clause dictates a separation of church and state. In Nevada, GOP Senate nominee Sharron Angle is drawing rebuke for running TV ads that portray Latino immigrants as criminals and gang members.

Perhaps the most dramatic tea party problems are in Alaska, where Republican Senate candidate Joe Miller is suffering another round of unfavorable headlines after it was revealed late Tuesday that he had admitted lying about his misconduct while working as a government lawyer in Fairbanks.

Miller was conducting his own poll in 2008 in an effort to oust a state GOP chairman, and he used his colleagues’ computers to vote in the survey, then erased their computers’ caches to try to hide what he had done.

“I was beyond stupid,” he wrote in a letter of apology included in documents ordered released by a judge Tuesday. He was suspended for three days without pay, according to the documents.
