Holly Solomon, 28, believes her family, and her unborn child, have a difficult life ahead of them over the four years because of the re-election of President Barack Obama.
She blamed his victory on her husband Daniel, who didn't cast a ballot, and was furious about the outcome of the election, investigators say.
Her husband, who is in critical condition after being run over on Saturday, said his wife 'just hated Obama.'
Witnesses told police that Solomon chased her husband around a parking lot near their home in Gilbert, Arizona, according to ABC 15 in Phoenix.
'He got out of the car and she was screaming at him. And he started walking away and she started driving in circles around him and she wouldn't let him go so finally he took off to try to get away and she ran into him,' a caller told 911 operators.
Mr Solomon reportedly tried to hide behind a light post as his wife circled him in her SUV and shouted at him for not doing enough to ensure Republican Mitt Romney won the election.
Even if Mr Solomon would have voted, the outcome of the election would not have changed.
Romney won Arizona and its electoral college votes by nearly ten percentage points, but he still lost the election by nearly 3.4million votes.
Holly Solomon was reportedly furious about the election results and convinced that 'Obamacare' - the president's controversial healthcare law - and other policies of the Obama administration would lead to hardship for the family.
Neighbors say the quiet neighborhood where the couple lives was highly polarized during the election -- but even here it was shocking to see violence erupt from it.
Holly Solomon was arrested on domestic violence charges of aggravated assault.
Police say she was not under the influence of drugs or alcohol at the time and is about six months pregnant.
